A 1×2 wavelength selective switch was designed. It consists of an arrayed-waveguide grating with fold-back paths, three 1×4 interleavers, and 1×2 switches. The number of crossings is independent of the number of wavelength channels.
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...
We designed a 200-GHz spacing, 20-ch, 1×4 wavefront control type Si wavelength selective switch. The device size was only 5070×4032 μm2. The configuration has no waveguide crossings regardless of the number of output ports and wavelength channels, which is a very important feature in silicon wire waveguide-based optical devices.
We designed and fabricated an integrated 14 wavelength selective switch using a silica planar lightwave circuit. The channel spacing is 100 GHz and the number of channels is 40. Signal switching experiments show the switch to be error-free and have low power penalty bit-error rate performance.
We demonstrate a multicasting operation in a wavelength selective switch composed of a liquid crystal on silicon (LCOS) and a multi-layered arrayed waveguide grating (AWG). By modulating the wavefront of an input light into a holographic shape with the LCOS, the input light is equally divided into six output beams. Measured power deviation is less than 1.61 dB and excess loss is less than 2.09 dB.
