Different types of optical fiber beam splitter or power splitter couplers are in use today. They have different applications. The splitter couplers that use coatings and have diachronic properties are more effective, and therefore, are in huge demand.
How To Attribute Dichroic Properties To A Fiber Power Splitter
To attribute dichroic properties to a fiber beam splitter, a single fiber from the glass is separated and then cut. The cut is made at the most appropriate angle after close measuring. The end surfaces of both angles are polished for perfection. After the completion of this process, a specific material that that possesses dichroic properties is added to the coupler. The material needs to be properly deposited. Once this is done, the cut halves should be rejoined. The cut halves of the fibers should face each other in angular position for better alignment.
The layer of material with dichroic properties that was deposited to the fiber receives light only after the third fiber is attached. The position of the third fiber will be at an angle. It is this angular position that enables the fiber to receive light from the dichroic layer.
Applications Of Optical Power Splitters
The introduction of optical beam splitter paved way for several inventions in modern science. The basic purpose of a power splitter is to divide a stream of light into two teams. The split beams can then be utilized in different ways in accordance with the demand of the application. Modern science has invented many applications that use two circuits. In optical systems, power splitters act as a circuit device to achieve higher level of flexibility in system operations. A good example of how fiber optical system works in a modern application would be the wavelength multiplexing systems in use today.
How To Increase The Information Capacity Of Couplers
The power splitters or couplers used today offer 0.8 to 0.9 um transmission rate of information. It can be increased up to 1.0 by way of utilizing sophisticated splitters. For this, the couplers need to have the ability to moonlight as multiplexer and should facilitate bidirectional transmission. Such couplers are also required to be small, rugged, and reliable.
Various researches and experiments are on the anvil to add increased usability and information transmission capabilities to beam splitter. Many of these experiments have been successful and the results are being applied in different applications.
