Giant Kerr nonlinearities and slow optical solitons in coupled double quantum-wells
نویسنده
چکیده
We show the formation of slow optical solitons in the asymmetric coupled double quantumwells (CQW) via a two-photon Raman resonance. With the consideration of real parameters in AlGaAs-based CQW, we indicate the possibility to have cancellation of the linear absorption and giant Kerr nonlinearities. With the controllable balance between dispersion and nonlinear effects in these solid-state based devices, this work may provide a practical platform for nonlinear optical signal processing. PACS numbers: 42.50.Gy, 42.65.Tg, 78.67.De

Giant Kerr nonlinearities and slow optical solitons in coupled double quantum-well nanostructure
a r t i c l e i n f o a b s t r a c t We investigate the enhancement of Kerr nonlinearities in an asymmetric coupled double quantum-well (CQW) by analyzing the nonlinear optical response. With the consideration of real parameters in AlGaAs-based CQWs, we indicate the possibility to obtain the giant Kerr nonlinearities with the cancellation of linear absorption simultaneously. We also reveal bot...
متن کاملUltraslow bright and dark solitons in semiconductor quantum wells
We study the low-intensity light pulse propagation through an asymmetric double quantum well via Fanotype interference based on intersubband transitions. The propagation of the pulse across the quantum well is studied analytically and numerically with the coupled Maxwell-Schrödinger equations. We show the generation of ultraslow bright and dark optical solitons in this system. Whether the solit...
متن کاملDark Optical Solitons: Physics and Applications
We present a detailed overview of the physics and applications of optical dark solitons: localized nonlinear waves (or ‘holes’) existing on a stable continuous wave (or extended finite-width) background. Together with the traditional problems involving properties of dark solitons of the defocusing cubic nonlinear Schrödinger equation, we also describe recent theoretical results on optical vorte...
متن کاملSpace charge effects on interband optical nonlinearities in asymmetric coupled quantum wells
We have studied space-charge-induced optical nonlinearities for asymmetric coupled quantum wells. By the spatial separation of heavy holes and electrons, an electrostatic potential is induced which increases the fundamental bandgap. Calculations, using the Hartree approximation, for oqtimi5ed AlGaAs structures show that a blue-shift of the band gap of 9 meV at a carrier density of 10 * cm can b...
متن کاملCavity-induced giant Kerr nonlinearities in a driven V -type atom
We discuss a simple and experimentally realizable model for creation of enhanced Kerr nonlinearities accompanied by vanishing absorption. The model involves a V -type atom subjected to a strong drive laser, a weak probe laser and coupled to a single-mode cavity field. Working in the bad-cavity limit, we find that the simultaneous coupling of the cavity field to both atomic transitions creates a...
