Nonlinear Dynamics in Semiconductor Lasers - Abstract
Coherent light-matter interactions arise when ultra-short pulse duration is smaller than medium polarization relaxation time $T_2$ . It allows to reversibly changing the state of the electromagnetic field and matter on an ultrafast time scale almost without energy losses, thus opening some new opportunities in optics. In the present talk, I present a study of different types of novel Coherent Photonics Devices (CPDs)? a novel optoelectronic devices based on coherent light-matter interactions. Among them? self-induced transparency passively mode-locked laser, which allows generating few-cycle laser pulses with ultrahigh repetition rate directly from compact laser oscillator [2,3]. The next example of CPD is angular laser beam deflector, which is based on ultrafast control of population inversion gratings in resonant medium coherently interacting with few-cycle light pulses . Finally, I present recently proposed method  for unipolar pulse generation in a Raman active medium excited by few-cycle optical pulses at superluminal velocity . References 1. Allen, J. H.
