Generation and Quenching of Intensity Pulsations in Semiconductor Lasers Coupled to External Cavities [PDF]
, 1980 The behavior of self-pulsing and nonpulsing lasers coupled to external cavities is investigated experimentally and theoretically. We investigate the dependence of the pulsation characteristics on the external cavity length using a saturable absorber ...

SILO-Radar: Self-Injection Locked Oscillator based Radar
, 2020 A compact Self-Injection Locked Oscillator based Doppler Radar (SILO-Radar) at 5 GHz has been studied, analytically and numerically. The SILO-Radar consists of just a cross-coupled oscillator and a Schottky diode baseband detector, with the help of the Hilbert transform at the baseband to extract the Doppler phase information.

Antiphase dynamics in a multimode semiconductor laser with optical injection [PDF]
, 2008 A detailed experimental study of antiphase dynamics in a two-mode semiconductor laser with optical injection is presented. The device is a specially designed Fabry-Perot laser that supports two primary modes with a THz frequency spacing. Injection in one

Accumulating regions of winding periodic orbits in optically driven lasers [PDF]
, 2001 We investigate the route to locking in class B lasers subject to optically injected light for injection strengths and detunings near a codimension-two saddle-node Hopf point.
