Microresonator frequency combs harness the nonlinear Kerr effect in an integrated optical
cavity to generate a multitude of phase-locked frequency lines. The line spacing can reach …

This paper numerically and experimentally investigates the performance of free-space
optical receiver using modes diversity coherent receipt under moderate-to-strong …

In this paper, the quadrature amplitude imbalance which may consist in I/Q demodulated
phase-sensitive optical time-domain reflectometry (-OTDR) is analyzed, which may happen …

Characterizing and real-time compensating the time-skew and phase-mismatch of the in-
phase and quadrature (I/Q) signals, for phase-sensitive optical time-domain reflectometry (Φ …

Digital coherent receivers employing Alamouti-coding are a promising solution for passive
optical networks (PON) with downstream rates of 100 Gb/s/λ. To reduce the cost by utilizing …

We propose a low-complexity and modulation-format-independent carrier phase estimation
(CPE) scheme based on two-stage modified blind phase search (MBPS) with linear …

This paper presents the architecture of a compact, robust, and broadly tunable RF receiver
based on photonic direct conversion and digital feed-forward lasers noise cancellation. In …

We demonstrate an ultra‐high‐speed transmission system‐based, all‐optical wavelength
conversion using Gaussian pulse shaping and 128 quadrature amplitude modulation. In this …

A novel method to simultaneously detect power imbalance, modulation strength, and bias
drift of coherent IQ transmitter during the initial power-up is presented. This is achieved by …

We experimentally demonstrated a one-span 100-km transmission of 64Gbaud/DP-16QAM
signal using a state-of-the-art InP-based coherent transmitter and receiver, a 1 …
