Abstract

Transmission properties of slow light in one dimensional photonic crystal coupled resonator waveguide have been investigated. By inserting multiple half-wavelength cavities discretely to forming CROW, the slow light band in photonic crystal bandgap can be broadened effectively. Otherwise cavities distance and refractive difference can flatten the rough pass band. By modulating these parameters, an optimized broadened flat pass band with 20.99nm has been obtained. Within the band, the group velocity is in the range of 0.0142c to 0.02148c. The propagation mechanism has been investigated via analysis of the field distribution in CROW.
