A 3.6 W/1484 nm CW cascaded phosphosilicate fiber Raman laser pumped by Yb-DCFL is reported. The threshold pump power, slope efficiency and conversion efficiency are 1.3 W, 33.4% and 30%, respectively.
A fully integrated 40-Gb/s transceiver fabricated in a 0.13-mum CMOS technology is presented. The receiver operates at a 20-GHz clock performing half-rate clock and data recovery. Despite the low fTof 70 GHz, the input sampler achieves 10-mV sensitivity using pulsed latches and inductive-peaking techniques. In order to minimize the feedback latency in the bang-bang controlled CDR loop, the proportional...
We have obtained tunable laser emission across both Tm3+ and Ho3+ transitions in a 0.79-mum pumped Tm3+, Ho3+-co-doped silica fibre laser. For a 2.3 m fibre a 1920-2125 nm tuning range was measured with 3.6 W maximum power.
A fully integrated 40-Gb/s transceiver is implemented in a 0.13-mum CMOS technology. This paper describes the challenges in designing a 20-GHz input sampler, a 20-GHz quadrature LC-VCO, a 20-GHz bang-bang phase detector, and a 40-Gb/s equalizer. The transceiver occupies 1.7 times 2.9 mm2 and dissipates 3.6 W from a 1.45-V supply. With the equalizer on, the transmit jitter of the 39-Gb/s 215-1 PRBS...
