Abstract

A compact arrayed-waveguide grating with small-bend waveguides incorporating air trenches and high mesa structures has been proposed. An 8-channel, 100-GHz-spacing silica arrayed-waveguide grating was fabricated, and its size was reduced dramatically to 1/4 of that of a conventional device.
