Generation and Detection of THz Waves Using Laser Chaos and Super Focusing with a Metal V-Grooved Wave Guide

A multi-GHz chaotic optoelectronic oscillator based on laser terminal voltage

“…In addition to the interest in optical microwave generation of periodic [1] and shapedpulse [2] signals, there has also been a stream of work on the generation of broadband chaotic signals through the use of electro-optic modulators subjected to feedback [7,8] of a laser diode (LD) subjected to optoelectronic [9] or optical feedback [10,11] (ECL), or to optical injection [12,13]. It is notable that certain applications [14] of chaotic laser dynamics, and in particular chaotic radar [15] and ultrahigh-rate random-bit generation [16][17][18], do not intrinsically make use of the chaotic optical signal, but of an electrical signal detected by one or more PDs.…”
