| Abstract: | We theoretically investigate the transmission properties of a cascade of cavities coupled to waveguide by the time domain coupled-mode theory. Based on the theoretical analysis, broad bandwidth optical waveguide intersections in photonic crystals are modeled and optimized. The transmission properties are simulated by finite-difference time-domain method and transmission coefficients higher than 98% for a wide frequency range between 0.360 (2πc/a) and 0.364 (2πc/a) are obtained. |
