JCS_V1_N2_RP5 S. K. Raghuwanshi Santosh Kumar Journal on Communication Engineering and Systems 2277-5242 1 2 23 26 Integrated optical taper waveguide, Matrix Method, Formal Electromagnetic Concepts Optical waveguides are the building blocks of photonics circuits. They are used as, couplers, switches, splitters, multiplexer and de-multiplexer for optical signals. During the last two decades extensive study on analytical/numerical method in the field of optical waveguide has been done by different researchers. In this paper the matrix method has been applied to analyze taper waveguide (or bend waveguide) while considering the normal incidence of light and assumed to be no reflection from the first medium, where the light is being launched. The waveguide is assumed to be taper (bend). This type of waveguide structure is used in WDM optical communication system as a power splitter device.
