Abstract

Optical nonlinearities in various materials pose some of the biggest challenges and opportunities in optical communications. Many important functions can be implemented using various forms of photonic nonlinear-interactions. Bit rate tunable all-optical noise mitigation of QPSK data signal and optical channel deaggregtion of QPSK signals are recent applications of nonlinear optical signal processing. In addition, optical tapped-delay-line (TDL) as a key building block in digital signal processing is discussed. Utilizing TDL, optical Nyquist generation of 32-Gbaud QPSK signals, and one/two dimensional optical correlation of 20-Gbaud QPSK signals are performed.
