TUNABLE ALL-OPTICAL DELAY VIA NONLINEAR OPTICAL PROCESSES IN SEMICONDUCTOR QUANTUM WELLS by SUSANTA
The dramatic experimental demonstration of slow light in atomic vapors via electromagnetically induced transparency (EIT) has stimulated considerable interest in the dynamic control of the group velocity of light and in the development of tunable all-optical delays. This dissertation presents experimental studies of all-optical tunable delays via nonlinear optical processes in semiconductor qua...
متن کاملSlow light using spin coherence and V-type electromagnetically induced transparency in [110] strained quantum wells
We model the slow-light phenomenon using electromagnetically induced transparency from spin coherence in [110] quantum wells. The long electron-spin lifetime in [110] quantum wells and the strain-induced shift of the light-hole-like excitonic transition energy below those of the heavy-hole-like continuum states can enhance the performance of slow light. The optical anisotropy due to band mixing...
متن کاملControlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency
In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...
متن کاملCoherent Optical Manipulation of Electron Spins in Semiconductor Nanostructures
Electron spin coherence can arise through a coherent superposition of two spin states in the conduction band of a semiconductor and can persist over remarkably long time and length scales. The robust nature of electron spin coherence makes it an excellent model system for exploring coherent quantum phenomena in semiconductors. This dissertation presents both spectral-and time-domain nonlinear o...
متن کاملSlow Light by Electromagnetically Induced Transparency ( EIT ) in Semiconductors
The ability to controllably slow down the propagation of light pulses can enable a variety of important applications. In recent years, two different approaches have been pursued for slow light. One approach explores dispersion engineering with passive optical elements such as resonators, filters, and photonic bandgap structures. The other approach takes advantage of coherent nonlinear optical p...
