Abstract:
A 32-channel 50 GHz spaced arrayed-waveguide grating(AWG) with our innovative configuration has been designed and fabricated. The performance of the device has been fully tested by using a system that consists of a tunable laser light source (TLS), an optical power meter and a polarization controller. The insertion loss (IS) of the device is 4.2–7.4 dB. The crosstalk is about −28 dB. TheIS uniformity is less than 3.3 dB. With our configuration, the performance of the device has been enhanced effectively and the difficulty in alignment process has been decreased obviously.
