Abstract

An arrayed waveguide grating (AWG) design method, believed to be novel, is proposed to achieve large channel count in a single stage. The method of irregularly sampled zero crossings with a spherical reference wave (MISZCSW) applies nonperiodic or irregular placement of apertures of the grating structure combined with holographic techniques based on zero crossings with a virtual spherical reference wave. As a result, the restriction of free spectral range (FSR) for the regular AWG is eliminated, and thus high channel count (>500) can be achieved in a single stage with reasonable noise level.
