Abstract
We describe a novel technique for passband control and shaping of an arrayed-waveguide grating (AWG) by designing the output star coupler to exhibit a parabolic deviation from the standard Rowland circle geometry. Passband broadening from 1 nm to 12 nm is possible using this approach. In principle, the phase-apodization function is equivalent to incorporating a synthetic aperture within the AWG, so that the same effect can be achieved by positioning a suitable aspheric-shaped anomalous refractive-index region within the arrayed-waveguide section of the device.
