Disorder or variation of the periodic structure of 1D-photonic crystal can lead to defects in the reflection band, characterized by one or more spectrally narrow transmission peaks inside that band. At or near such defects, changes in the effective group velocity of the light result in interesting optical phenomena such as Faraday rotation enhancement and gain enhancement in a distributed feedback (DFB) photonic crystal laser. In this talk, we present experimental results on and a theoretical interpretation of magneto-optic rotation and DFB lasing within the reflection band of CLiPS polymer multilayers.
