TL;DR: In this article, a double heterostructure laser has been fabricated on a semi-insulating GaAs substrate, with threshold currents as low as 15 mA for a cavity length of 100 μm.

TL;DR: It is reported that the first room temperature CW operation of two dimensional single-mode edge-emitting photonic crystal Bragg lasers with single-lobed, diffraction limited far-fields is obtained.

TL;DR: In this article, a bistable laser with an antireflection coating on one facet is used for digital optical disk readout, where the optical switching is accompanied by a switching of the voltage across the absorber section.

TL;DR: A vector-matrix multiplier with simple charge-domain multiply-accumulate units has been implemented that computes the product of a binary vector and an analog matrix of charge, providing an analog output vector.

TL;DR: Wave-optics calculations of the temporal and spatial evolution from random noise of a double phase-conjugate mirror in photorefractive media that show its image exchange and phase-reversal properties show that for values of coupling coefficient times length greater than two the process exhibits excellent conjugation fidelity, behaves as an oscillator, and continues to operate even when the noise required for starting it is set to zero.
