PC ring resonator have many advantages such as scalability in size, flexibility in design, versatility of a ring-shape, low loss with high quality factor, no size-dependent bending loss and high spectral selectivity. In this report, we have been analyzed add drop filters and power splitters based on multiple parallel Photonic Crystal ring resonator. Designed structure can be used as a optimized add drop filter in the wavelength and power splitter in the. . M3 ER -
