We demonstrate multi-impairment monitoring of 640 Gb/s signals enabled by a broadband photonic-chip-based radio-frequency spectrum analyser. We show simultaneous monitoring of group velocity dispersion, in-band optical signal-to-noise ratio and timing jitter from a single measurement.
A review of the development and applications of compact highly nonlinear Chalcogenide waveguides for ultra-fast all-optical signal processing is presented. We demonstrate the extreme tapering of a highly nonlinear As2S3 fiber to further increase its nonlinearity by more than an order of magnitude thereby enabling time-division demultiplexing of a 160 Gb/s signal by four-wave mixing (FWM) with significantly...
Chalcogenide glasses offer large ultrafast third-order nonlinearities, combined with low two-photon absorption and absence of free carrier absorption in a photosensitivity medium. This unique combination of properties is nearly ideal for all-optical signal processing devices. In this paper we review the key properties of these materials, outline progress in the field and focus on several recent highlights:...
A 4-channel optical transceiver chipset is designed in a 0.18 mum standard CMOS technology for the applications of automotive wired networks. The transmitter LD driver operate at 1 Gb/s with reliable APC (30-70 mA) and AMC (20-80 mApp) controls, whereas the receiver TIA demonstrates 76.6 dBOmega transimpedance gain and 724 MHz bandwidth against the very large input parasitic capacitance (6 pF) with...
