We propose a compact polarization diversity optical circuit using silica waveguides and photonic crystal waveplates. By setting these circuits at the front and rear of the silicon optical devices, the polarization dependence of the silicon devices...

Processing ultra-fast optical signals without optical/electronic conversion is in demand and time-to-space conversion has been proposed as an effective solution. We have designed and fabricated an arrayed-waveguide grating (AWG) based optical spec...
We designed and fabricated an integrated 1 x 4 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 ...
We introduce and demonstrate an ultra-compact 5x5 waveband cross-connect module that can process 80 channels (50-GHz spacing) per fiber; it combines 50-100-GHz interleavers and two 5 x 5 waveband cross-connect (WBXC) modules with 100-GHz channel s...
