A 6-channel drop filter with resonant micro-cavityreflector is designed based on the resonant coupled theory between the 2d photonic crystal waveguide and the 2d photonic crystal micro-cavity.
For a given cavity length, the parameters, including the curvature of reflector, waist radius and spot size on reflectors, are calculated according to the Gaussian profile.

By using a laser cavity which consists of only two gratings and a resonant reflector, a N2-laser-pumped dye laser with a spectral linewidth of 1.3 GHz has been made.
