Modeling of a Resonant Tunneling Diode Optical Modulator

J. J. N. Calado, J. M. L. Figueiredo, C. N. Ironside

The integration of a double barrier resonant tunneling diode within a unipolar optical waveguide provides electrical gain over a wide bandwidth. Due to the non-linearities introduc…

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…

A quantum coherent approach to transport and noise in double barrier resonant diodes: shot noise a way to distinguish coherent from sequential tunneling

V. Ya. Aleshkin, L. Reggiani, N. V. Alkeev +4

We implement a quantum approach which includes long range Coulomb interaction and investigate current voltage characteristics and shot noise in double barrier resonant diodes. Theo…
