Dynamic non-linear optical processes in semiconductors

Optical interconnects to silicon

“…Smith [5] published a more optimistic analysis of optical logic devices in which he argued that the use of resonator structures could reduce the operating energy below electronic devices. The nonlinear effects in semiconductors became relatively well understood [6]. These semiconductor bistable devices were very simple, with some (e.g., [4]) requiring only a semiconductor material with plane parallel surfaces.…”

Photon accelerator: Large blueshifting of femtosecond pulses in semiconductors

“…Effects of recombination and diffusion are, therefore, neglected. It should be noted that the carrier recombination (both radiative and nonradiative) takes place typically on nanosecond or even longer time scales [2]. These times are much longer than the time scales of the duration of the processes described by our model.…”

“…TPA is a nonlinear resonant process in which an interband transition is induced by the simultaneous absorption of a pair of photons. For photon energies in excess of half the band gap energy, TPA generates free carriers which contribute to nonlinear refraction [2]. In conventional approaches, the TPA contribution is limited to the imaginary part of the third-order susceptibility $3) which determines the third-order induced polarization P(3) in the wave equation [3] .…”

Control of nonlinear absorption and amplification of light in Er^3+-doped fluoroindate glass

“…[1][2][3] This phenomenon has been investigated in media with a variety of mechanisms, for the study of light-matter interaction, and in various applications. For example, the interaction between two beams can be demonstrated in laserinduced grating experiments, such as in Kerr-like media 4 and in photorefractive materials, 5 and in cross-phasemodulation experiments.…”
