Time-Stretch Analog-to-Digital Conversion Using Phase Modulation and Broadband Balanced Coherent Detection for Improving Resolution
Fiber optics links subsystems Radio frequency photonics
2015/5/22
We introduce a novel implementation of time-stretch analog-to-digital conversion which uses phase modulation and balanced coherent detection for improving resolution. Proof of concept experiment demon...
Ultimate Single-Carrier Recovery for Coherent Detection
Ultimate Single-Carrier Recovery Coherent Detection
2015/5/20
Proposed adaptive decision-feedback CR method is “ultimate” in the sense that it is ML/MMSE optimal (its performance cannot ever be exceeded) while its complexity vs. the num-ber of taps, L, is lowest...
8b10b Line Coding of PSK Signals for Effective Homodyne Coherent Detection
Line Coding PSK Signals Homodyne Coherent Detection
2015/5/15
We demonstrate effective homodyne optical phase locking to a phase-shift-keying (PSK) signal with residual carrier by exploiting 8b10b coding. Low-penalty transmission over 215 km of installed dispers...
Compensating XPM for 100 Gbit/s coherent channels with 10 Gbit/s direct-detection NRZ neighbors
Fiber optics communications Modulation
2015/6/9
We propose a simple optoelectronic method to compensate for cross-phase modulation in long-haul systems. Simulations show >1.3 dB improvement in Q for 1200-km 40 and 100-Gbit/s CO-QPSK and CO-OFDM cha...
100 Gb/s Per-Channel Free-Space Optical Transmission with Coherent Detection and MIMO Processing
Per-Channel Free-Space Optical Transmission Coherent Detection MIMO Processing
2015/7/20
We experimentally demonstrate the first 100 Gb/s per-channel free-space optical transmission using polarization-multiplexed QPSK, coherent detection, and MIMO processing. This is the highest per-chann...
111 Gb/s Transmission with Compensation of FBG-induced Phase Ripple Enabled by Coherent Detection and Digital Signal Processing
FBG-induced Phase Ripple Enabled Coherent Detection Digital Signal Processing
2015/7/17
We demonstrate that coherent detection combined with digital signal processing can completely compensate for FBG induced phase-ripple. We report penalty free transmission of 40x111-Gb/s POLMUX-RZ-DQPS...
Use of the Zero Forcing Method for Compensation of Polarization Dependent Loss in Coherent Fiber-Optic Links
Zero Forcing Method Compensation Polarization Dependent Coherent Fiber-Optic Links
2015/7/17
We show that a zero forcing receiver can be used to achieve nearly optimal performance in coherent polarization multiplexed systems. The advantage is in the receiver simplicity relative to the joint d...
