Coherent Population Trapping of Electron Spins in a Semiconductor
Kai-Mei C. Fu, Charles Santori, Colin Stanley +2
In high-purity n-type GaAs under strong magnetic field, we are able to isolate a lambda system composed of two Zeeman states of neutral-donor bound electrons and the lowest Zeeman…
Optical modulation at around 1550 nm in a InGaAlAs optical waveguide containing a InGaAs/AlAs resonant tunnelling diode
J. M. L. Figueiredo, A. R. Boyd, C. R. Stanley +3
We report electro-absorption modulation of light at around 1550 nm in a unipolar InGaAlAs optical waveguide containing a InGaAs/AlAs double-barrier resonant tunneling diode (DB-RTD…
Optical modulation in a resonant tunneling relaxation oscillator
J. M. L. Figueiredo, C. R. Stanley, A. R. Boyd +1
We report high speed optical modulation in a resonant tunneling relaxation oscillator consisting of a resonant tunneling diode (RTD) integrated with a unipolar optical waveguide an…
Ultra-low voltage resonant tunnelling diode electroabsorption modulator
J. M. L. Figueiredo, C. N. Ironside, C. R. Stanley
Embedding a double barrier resonant tunnelling diode (RTD) in an unipolar InGaAlAs optical waveguide gives rise to a very low driving voltage electroabsorption modulator (EAM) at o…
Electric field switching in a resonant tunneling diode electroabsorption modulator
J. M. L. Figueiredo, C. N. Ironside, C. R. Stanley
The basic mechanism underlying electric field switching produced by a resonant tunnelling diode (RTD) is analysed and the theory compared with experimental results; agreement to wi…
Terahertz-induced depletion of the ground-state population of neutral donors in GaAs measured by resonant elastic light scattering from donor-bound excitons
D. G. Allen, C. R. Stanley, M. S. Sherwin
Strong resonant elastic light scattering (RELS) from the donor-bound exciton transition in GaAs (1.514eV) occurs at neutral donors in the ground (1S) state, but not at neutral dono…
