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…
