We realize a 32-channel InP-based arrayed-waveguide grating (AWG) with a 5-GHz channel spacing. The AWG shows approximately 14 dB excess-loss, 9 dB crosstalk, and 21 times 22 mm2 dimensions.
We demonstrate for the first time the phase-error compensation for a 20-GHz-spacing InP AWG with electro-optic phase shifters placed on 42 arrayed waveguides. The experiment results show successful phase control and 6-dB reduction of crosstalk.
We realize a high-precision 10-channel InP-based arrayed-waveguide grating (AWG) with a 10-GHz channel spacing. The AWG showed approximately 10 dB excess-loss, 10 dB crosstalk, and 8.2 times 6.8 mm2 dimensions.
The phase errors of a 20 GHz AWG fabricated on InP are determined by measuring the intensity and phase of the pulse train produced by the transmission of a short pulse through an AWG.
A very compact InP-Based 16-channel O-CDMA encoder-/decoder chip (3.8 mm x 6.8 mm) has been designed, fabricated and characterized. The device successfully performs O-CDMA spectral encoding.
