This letter reports on 10-GHz and 20-GHz channel-spacing arrayed waveguide gratings (AWGs) based on InP technology. The dimensions of the AWGs are 6.8 times 8.2 mm2 and 5.0 times 6.0 mm2, respectively, and the devices show crosstalk levels of -12 dB for the 10-GHz and -17 dB for the 20-GHz AWG without any compensation for the phase errors in the arrayed waveguides. The root-mean-square phase errors...
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.
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.
We present first results on heteroepitaxy of InP on silicon on insulator (SOI). We also demonstrate InP nanopillar fabrication by means of selective epitaxy. Selective epitaxy is also exploited to fabricate advanced photonic integrated devices for optical code division multiplex access (OCDMA) networking applications.
We report error-free spectral encoding and decoding operation of an InP monolithic, ultra-compact optical-CDMA encoder/decoder photonic chip pair. The experimental results demonstrate the strong potential for realizing high performance O-CDMA networks with InP micro-systems
