Abstract

type:post print

We designed and fabricated 70×75μm^2 arrayed waveguide grating demultiplexer consisting of Si slab and wire waveguides on a silicon-on-insulator substrate. By optimizing the connection between components and the layout of arrayed waveguides, internal light scattering and the increase in phase error were suppressed. As a result, clear demultiplexing characteristics were observed with a channel spacing of 8 nm and a sidelobe level of-22 dB in the wavelength range from 1.5 to 1.6μm.
