Abstract :
A 200-GHz spacing, 17-channel, 1×2 wavelength selective switch was fabricated using silicon wire waveguides. An arrayed-waveguide grating with loopback is used to configure the 1×2 wavelength selective switch. The chip size was only 2.8 mm × 6.5 mm. The minimum and the maximum losses of the wavelength selective switch were 21 dB and 26 dB, respectively. The minimum and the maximum crosstalks were -21 dB and -2 dB, respectively.
