 A two-dimensional (2-D) photonic crystal ring resonator-based bandstop filter is conceived, its stopband efficiency is investigated using the 2-D finite difference time domain method, and its band diagram is calculated by plane wave expansion method. The stop-band efficiency of the filter, ∼98%, is observed over the wavelength range 1562–1573 nm. Furthermore, the effects of the relative permittivity and geometrical parameters are considered for determining stop-band efficiency and stop-band width. The overall dimension of the device is 11.4 × 11.4 μm, which is highly suitable for photonic integrated circuits.
