Full-Field, Carrier-Less, Polarization-Diversity, Direct Detection Receiver based on Phase Retrieval [PDF]
, 2019 We realize dual-polarization full-field recovery using intensity only measurements and phase retrieval techniques based on dispersive elements. 30-Gbaud QPSK waveforms are transmitted over 520-km standard single-mode fiber and equalized from the receiver

All-optical 2R regeneration using the hysteresis in a distributed feedback laser diode [PDF]
, 2010 A broadband optical 2R regenerator based on a single distributed feedback laser is demonstrated for nonreturn to zero signals at a bitrate of 10 Gb/s. A semi-analytical approach for the influence of hysteresis on the transfer function of a 2R regenerator

In-band Perturbation based OSNR Estimation
, 2020 Perturbed spectra are modelled to estimate OSNR for a single channel amplified link. Perturbation-dependent nonlinear noise is separated from constant ASE noise using a set of propagated perturbed spectra. A least mean square fitting is used to estimate OSNR with standard deviation of 0.16 dB.

OSNR Monitoring for NRZ-PSK Signals Using Silicon Waveguide Two-Photon Absorption
IEEE Photonics Journal, 2011 We study the use of two-photon absorption (TPA) in a silicon optical waveguide for measuring the optical signal-to-noise ratio (OSNR) of a nonreturn to zero phase-shift keying (NRZ-PSK) signal.
