We report on 10 gigabit Ethernet (IEEE 802.3ae) fiber-optic transmission at 1.3 mum wavelengh utilizing high-speed GaNAsSb uni-travelling-carrier photodetectors (PDs) grown on GaAs substrate. With an optical bandgap of ~0.88 eV, the PDs are suitable for near-infrared operation up to wavelengths of about 1380 nm. The dc responsivity and 3-dB cut-off frequency of the non-antireflection-coated PD at...
We introduce a cost-effective OCDMA/RoF system on PON for broadband service delivery independent of the user’s location. Successful simulation results on 16-QAM transmitted downstream at 250 MS/s are discussed.
We demonstrate an all-optical scheme for routing radio signals through optical fibres employing label-processing technique. 10-MS/s 64-QAM signal carried on 5-GHz RF carrier was successfully routed with EVM of 1.81%.
We demonstrate for the first time 160 Gbps error-free 1times4 all-optical packet switching including all-optical label rewriting. Power penalty 1.5 dB enables application in multihop packet-switched networks.
Advanced optically-emulated x-QAM techniques and the modal dispersion-robust radio-over-fiber OFM technique enable the delivery of high-capacity data via a single multimode (silica or polymer) optical fiber in-building network to wired as well as wireless terminals.
We demonstrate ≪10ps recovery in a monolithically integrated all-optical wavelength converter chip. This recovery time enables error-free wavelength conversion of 80-Gb/s data streams.
