Abstract :
In this letter, we demonstrate an optical demultiplexer on the silicon-on-insulator material employing the turning-mirror-integrated arrayed-waveguide grating (AWG). We substitute the bent waveguide array in the traditional AWG configuration by adopting the structure of the turning-mirror-integrated straight waveguides. Description of the design procedure is provided. The crosstalk of the fabricated 1×4 AWG is better than -23.1 dB. The typical on-chip insertion loss is about -8 dB and the output nonuniformity is less than 0.4 dB. The polarization-dependent central wavelength shift is about 0.068 nm.
