Abstract

An arrayed-waveguide grating (AWG) demulti-plexer1–3 is one of the key devices of wavelength division multiplexing systems. Considerable efforts have been made to improve the performance of the AWG demultiplexer. For example, the insertion loss has been reduced using a vertically tapered waveguide.4 It should be noted that most of the efforts have so far been directed toward modification of an arrayed-waveguide. In this paper, we propose a new technique of reducing the insertion loss. Phase adjustment elements called islands are introduced in the first and second slabs. The configuration of the island is designed using a local phase-velocity principle. Calculation based on the beam-propagation method (BPM) shows that the insertion loss is reduced from 9.3 dB to 1.3 dB by the addition of the islands.
