Abstract :
A novel three-port resonant cavity in two-dimensional photonic crystals (2D PCs) with two wavelength-selective reflection micro-cavities is proposed. In the structure, three micro-cavities are used. One is used for a resonant tunneling-based input waveguide and the others are used to realize wavelength-selective reflection feedback. According to coupled mode theory in time, the conditions to achieve ultra-high quality in the system are derived thoroughly. The performance of the designed resonant cavity has been numerically calculated by using the finite-difference time domain (FDTD) method and the results imply that the design is feasible.
