Tunable radio frequency photonics filter using a comb-based optical tapped delay line with an optical nonlinear multiplexer

摘要

A radio frequency (RF) photonic filter is experimentally demonstrated using an optical tapped delay line (TDL) based on an optical frequency comb and a periodically poled lithium niobate (PPLN) waveguide as multiplexer. The approach is used to implement RF filters with variable bandwidth, shape, and center-frequency. (C) 2015 Optical Society of America
