A new ultra-high sensitivity, low-power optical receiver based on a decision-feedback equalizer
Fiber optics links and subsystems Fiber optics sources and detectors Optical interconnects
2015/5/21
A decision-feedback equalizer is used to recover data at baud rates far above the bandwidth of a low-noise TIA front-end. The overall 90-nm CMOS DC-coupled clocked receiver has better than -25 dBm pow...
High-Sensitivity Phase Noise Monitoring Using a Phase-Asymmetric Nonlinear Loop Mirror
High-Sensitivity Phase Noise Nonlinear Loop Mirror
2015/5/15
A high-sensitivity phase noise (PN) monitoring technique is proposed and demonstrated using a phase-asymmetric nonlinear loop mirror (PANLM). The phase-error variations from 4 0 to 52 0 are extracted ...
Optical Biasing in Direct Detection Optical-OFDM for Improving Receiver Sensitivity
Fiber optics communications Modulation
2015/6/4
We show that replacing of electrical by an optical biasing minimizes the nonlinearity effect of an optical modulator. This allows the amplitude of the driving signal to be increased which increases th...
