Ultra-low-voltage Micro-ring Modulator Integrated with a CMOS Feed-forward Equalization Driver
Waveguide modulators Photonic integrated circuits
2015/5/26
We present an all-CMOS micro-ring modulator packaged with a feed-forward equalization driver circuit, operating in charge-injection mode at 8 Gbps with a drive voltage of only 50 mVp-p and a power con...
Simple and Scalable WDM/TDMA-PON using Spectral Slicing and Forward Error Correction
Fiber optics communications Networks combinatorial network design
2015/5/22
We describe a simple and scalable WDM/TDMA PON system that uses spectral slicing and FEC in burst-mode upstream transmissions. The sensitivity was improved to -31.5 dB at a sliced bandwidth of 400 GHz...
Soft-decision Forward Error Correction in a 40-nm ASIC for 100-Gbps OTN Applications
40-nm ASIC OTN Application Error Correction
2015/5/15
Soft-decision forward error correction provides high coding gain, but typically with high complexity. We present a soft-decision turbo product code with >11 dB NECG and reasonable complexity in a 40-n...
Unrepeatered Transmission over 300 km of NZDSF Using 8x112-Gb/s Time-Interleaved RZ-PDM-QPSK with Coherent Detection and Forward Raman Pumping
Unrepeatered Transmission Coherent Detection RZ-PDM-QPSK
2015/5/15
We show that time-interleaved RZ-PDM-QPSK and forward Raman pumping can increase the performance of a 112-Gb/s PDM-QPSK coherent unrepeatered transmission system over 300 km of NZDSF by more than 2 dB...
