In-Line Polarizer is up for Grab Now at Best Low Price!

A polarizer is an optical filter which is used to pass light waves of a specific polarization blocking other light waves. The In-Line Polarizer is used for converting un-polarized light into polarized light having the high extinction ratio. What does the polarizer do specifically? The light wave of a specific polarization at slow or fast axis is passed effectively and the other waves are blocked. So use of it in fiber lasers, amplifiers, and communication system helps in the better maintenance of the system.

Two Types Of Polarization Beam Combiners & Splitters

Polarizing Beam combiners / splitters are the devices used to combine two polarized light signals or split single non-polarized light into two polarized parts. These combiners and splitters are designed and developed to split light beams by deploying the polarization state and not by wavelength or intensity.

The polarizing beam splitters / combiners typically have 0° or 45° angle of incidence and a 90° division between the beams; this generally depends on the configuration. There are two types of Polarization beam combiners / splitters; these are described below:

  1. Incoherent Polarization Combining / Splitting

The Incoherent combining or splitting is the simpler variant and the basic technique. In this method, the resulted beams of two broad area laser diodes are sent onto a thin-film polarizer so as to reflect one of the beams while transmit the other; both of these beams then propagate in the same direction. As a result, one attains an unpolarized beam (with the combined optical power of the input beams) and the same beam quality. Consequently, the brightness gets nearly doubled.

This technique is often used for any-a-applications, for instance, end-pumping of a solid state laser with an increased power. However, the technique is not suitable for power scaling.

  1. Coherent Polarization Combining / Splitting

With coherent beam combining or splitting it is viable to attain a linear polarized state in the output, if two mutually coherent beams are combined. If two ports have the equal input powers, the output polarization would be typically rotated by 45° -depending on the polarization direction of any of the input beams.

Also, the coherent polarization combining can be repeated several times because of the linear output polarization. Thereby, this technique is suitable for power scaling.

A polarization beam combiner and splitter is often used in photonics instrumentation, optics and semiconductors to transmit p-polarized light while reflecting s-polarized light. These hold a world of worth when it comes to optics, telecommunication and fiber applications, and make the working effective as well as effortless.

Selection Guideline for Polarization Maintaining Optical Circulator

There are very many passive components involved in fiber optical networks and an optical circulator is among the top options. These components help in signal delivery without any failure thus remain to be very important. When used, the optical circulator will direct the signals between different ports but maintaining a single direction. There will be no chances of the signal going in a different direction that was not intended.

Two-way situations apply

However, that does not make it a one-direction device only. There are rare situations where you can have the circulator used in a two-way situation. When there is an optical signal sent by the circulator in two different directions, the fiber is usually one. You will have the circulator fixed on the two ends of the fiber and will function by adding a signal in one end while removing from the opposite end.

Whenever you are choosing a Polarization Maintaining Optical Circulator to use, there are very many things that must be put into serious consideration. That will be the benchmark on which your choices will be based upon. Features must be one of the things that you look out for in an ideal optical circulator. The good thing is that such a circulator comes loaded with more features to make your experience remarkable.

Consider different applications

The circulator comes with two main high-power options to choose from. You can go for either 1550nm or 1064nm depending on your needs. The other standout features for Polarization Maintaining Optical Circulator include epoxy-free optical path and compact inline package. There are additional features that as well make the circulator a unique choice compared to other alternatives available.

The other thing to look at includes applications which play a key role in the functioning of an optical circulator. Main applications that you should pay attention to are bidirectional pumping, fiber sensors, add-drop multiplexing, bidirectional signal transmission systems as well as coupling inline chromatic dispersion compensation devices.

With these applications, you are sure that your circulator will give out an optimal performance. You can have a Polarization Maintaining Optical Circulator used in multiple optical settings thus it will offer you limitless options. That is because they are unidirectional and non-reciprocating while their availability as three-port makes the circulator even more suitable. Do you know that it’s possible to use optical circulators in communication systems that are more advanced? Well, that is yet another of their biggest advantage over other types of circulators.

Get optimal performance

That is made possible by the fact that optical circulators come with a very small insertion loss while their isolation levels are very high. When used in advanced systems of communication, the circulators will come as any of the common applications. The result you get from using Polarization Maintaining Optical Circulator will depend largely on how you have chosen to use it.  If you make your decision well, the result will be good but if not then you will get a different result. It will all depend on your choices.

Introduction of Fiber Optic Coupler with its Benefits & Classification

A fiber optic coupler is an indispensable part of the world of electrical devices. Without these no signals would be transmitted or converted from inputs to outputs. This is the reason these are so important thereby this article discussed about these, introduction, classification and benefits in detail.

Fiber Optic Coupler is an optical cog that is capable of connecting single or multiple fiber ends in order to permit the broadcast of light waves in manifold paths. This optical device is also capable of coalescing two or more inputs into a single output while dividing a single input into two or more outputs. In comparison to a connector or a splice, the signals may be even more attenuated by FOC i.e. Fiber Optic Couplers; this is due to the division of input signal amongst the output ports.

Types of Fiber Optic Coupler

Fiber Optic Couplers are broadly classified into two, the active or passive devices. For the operation of active fiber coupler an external power source is required, conversely no power is needed when it comes to operate the passive fiber optic couplers.

Fiber Optic Couplers can be of different types for instance X couplers, PM Fiber Couplers, combiners, stars, splitters and trees etc. Let’s discuss the function of each of the type of the Fiber Optic Couplers:

Combiners: This type of Fiber Optic Coupler combines two signals and yields single output.

Splitters: These supply multiple (two) outputs by using the single optical signal. The splitters can be categorized into T couplers and Y couplers, with the former having an irregular power distribution and latter with equal power allocation.

Tree Couplers: The Tree couplers execute both the functions of combiners as well as splitters in just one device. This categorization is typically based upon the number of inputs and outputs ports. These are either single input with a multi-output or multi-input with a single output.

PM Coupler: This stands for Polarization Maintaining Fiber Coupler. It is a device which either coalesces the luminosity signals from two PM fibers into a one PM fiber, or splits the light rays from the input PM fiber into multiple output PM fibers. Its applications include PM fiber interferometers, signal monitoring in its systems, and also power sharing in polarization sensitive systems etc.

Star Coupler: The role of star coupler is to distribute power from the inputs to the outputs.

Benefits of Fiber Optical Couplers

There are several benefits of using fiber optic couplers. Such as:

  • Low excess loss,
  • High reliability,
  • High stability,
  • Dual operating window,
  • Low polarization dependent loss,
  • High directivity and Stumpy insertion loss.

The listed benefits of Fiber Optical Couplers make them ideal for many applications for instance community antenna networks, optical communication systems and fiber-to-home technology etc.
