    Abstract

    This letter reports a spectral phase encoder using an arrayed-waveguide grating (AWG) with phase-adjustable structure. It consists of the 12.5-GHz spacing eight-channel AWG phase-adjustable structure with deep trenches formed in the waveguides. The spectral phase encoding of optical short pulses at the repetition rate of 12.5 GHz using the AWG encoder was successfully demonstrated.
