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…

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…
