Electro-optical Simulation of a-Si Thin-Film-Transistor Liquid Crystal Display Pixels [PDF]

open access: yes, 2001
An analysis of an amorphous silicon (a-Si) thin-film-transistor liquid-crystal display (TFT-LCD) pixel is presented. The electro-optical model combines the electrical properties of the switching element and the optical performance of a twisted nematic ...

The dressed atom as binary phase modulator: towards attojoule/edge optical phase-shift keying

open access: yes, 2010
Nanophotonic technologies offer great promise for ultra-low power optical signal processing, but relatively few nonlinear-optical phenomena have yet been explored as bases for robust digital modulation/switching~\cite{Yang07,Fara08,Liu10,Noza10}. Here we

Nonlinear adiabatic optical isolator [PDF]

open access: yes, 2016
We theoretically propose a method for optical isolation based on adiabatic nonlinear sum frequency generation in a chirped quasi-phase-matching crystal with strong absorption at the generated sum frequency wave.

Silicon Non-Blocking 4 × 4 Optical Switch Chip Integrated With Both Thermal and Electro-Optic Tuners

open access: yesIEEE Photonics Journal, 2019
We experimentally demonstrate an integrated strictly non-blocking silicon 4 × 4 optical switch chip that can be operated in both thermo-optic (TO) and electro-optic (EO) switching modes.

Optical bistability in a GaAs based polariton diode

open access: yes, 2008
We report on a new type of optical nonlinearity in a polariton p-i-n microcavity. Abrupt switching between the strong and weak coupling regime is induced by controlling the electric field within the cavity.

Demonstration of wavelength packet switched radio-over-fiber system [PDF]

open access: yes, 2007
The authors present a novel concept of employing optical wavelength packet switching in radio-over-fiber access networks. In such a system, the tunable laser (TL) would be employed as a transmitter in the central station. The optical carrier generated by

Single shot ultrafast all optical magnetization switching of ferromagnetic Co/Pt multilayers [PDF]

open access: yes, 2017
In a number of recent experiments, it has been shown that femtosecond laser pulses can control magnetization on picosecond timescales, which is at least an order of magnitude faster compared to conventional magnetization dynamics.

Controlled multiple spectral hole burning via a tripod-type atomic medium

open access: yesNew Journal of Physics
In limit of saturation spectroscopy, we theoretically study the spectral hole burning (SHB) in the absorption spectrum of a probe field through a tripod atomic system. The response function for the probe field is calculated in a Doppler-broadened medium.

New Photonic System for Optical Packet Switching [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2003
Fast optical switching (ms timebase) is realized by using a RF frequency tone inserted in the optical packet that carries a digital payload. By using a highly selective RF filtering for optical packet header frequency recognition, we have obtained ...
