| Research Abstract |
The optical spectrum control circuit using an arrayed-waveguide grating(AWG), which is proposed in this paper, has flat spectral response and can control both spectral phase and amplitude of optical signal. The AWG had a free spectral range(FSR) of 100 GHz, 45 waveguides in the waveguide array, and 90 channel waveguides with a phase shifter. The chip size was 72. 3 mm x 31. 4 mm. The insertion losses at the center frequency and at the outer end frequency were 7. 2 dB and 9. 4 dB, respectively. It could control the chromatic dispersion up to-1200 ps/nm.
