WDM based on multimode interference-coupler built in an organic–inorganic material

The WDM phasar, which is a key element in optical telecommunication systems, is shown here to be made with a very low cost and promising technology based on organic–inorganic material, and with a design based on MMI devices for the splitter and the combiner instead of star couplers or gratings. A re...

Description
Summary:The WDM phasar, which is a key element in optical telecommunication systems, is shown here to be made with a very low cost and promising technology based on organic–inorganic material, and with a design based on MMI devices for the splitter and the combiner instead of star couplers or gratings. A realization of a first 4×4 MMI phasar, for use around 1.55 μm wavelength, demonstrates the application of these two specific aspects. Experimental measurements and theoretical results are compared.
