GaAs optoelectronic neuron arrays.
A simple optoelectronic circuit integrated monolithically in GaAs to implement sigmoidal neuron responses is presented. The circuit integrates a light-emitting diode with one or two transistors and one or two photodetectors. The design considerations for building arrays with densities of up to 10(4) cm(-2) are discussed.
متن کاملSelf-assembled quantum dots on GaAs for optoelectronic applications
In the past 20 years the semiconductor laser has become a key device in optical electronics because of its pure output spectrum and high quantum efficiency. As the capabilities of laser diodes have grown, so has the range of applications contemplated for them. The laser performance successes gained using quantum wells in optoelectronic devices can be extended by adopting quantum dot structures....
متن کامل2=picosecond, GaAs photodiode optoelectronic circuit for optical correlation applications
An ultrafast GaAs Schottky photodiode is monolithically integrated with a microwave detector. By using this new optoelectronic circuit.in place of a nonlinear crystal in an optical correlation setup, the high-speed photodiode can measure laser pulse durations without using expensive sampling oscilloscopes. Key advantages are that this circuit works over a broad wavelength range and at low peak ...
متن کاملReconfigurable optoelectronic interconnects for VLSI circuits based on fibre arrays
The aim of the presented work is to realise optical interconnects based on two-dimensional (2D) fibre arrays for the board-to-board area in order to overcome bandwidth problems caused by planar bus structures in computing systems. Due to arising mechanical, optical and thermal problems in board-to-board area free space optical interconnects are not recommendable. Therefore fibre-based connectio...
متن کاملOptical sensor arrays for chemical sensing: the optoelectronic nose.
A comprehensive review is presented on the development and state of the art of colorimetric and fluorometric sensor arrays. Optical arrays based on chemoresponsive colorants (dyes and nanoporous pigments) probe the chemical reactivity of analytes, rather than their physical properties. This provides a high dimensionality to chemical sensing that permits high sensitivity (often down to ppb level...
