The algorithmic, electronic, and optical aspects of the implementation of a perfect-shuffle interconnected bitonic sorter are analyzed. The performance metrics such as the bit output data rate and the power consumption of the system are quantified. T

This letter describes the performance of electro-absorption optical modulator structures, based on strain-balanced InGaAs/AlGaAs p-i-n multiple quantum wells (MQWs). It specifically considers the influence of lattice mismatch with the graded InGaAlAs

We demonstrate a self‐electro‐optic effect device (SEED) designed to work at 1047 nm to match the high power available from a Nd:YLF laser. The device uses a strain‐balanced InGaAs/GaAs multiple quantum well grown on a GaAs substrate with an In

We propose and demonstrate a novel electroabsorptive device which possesses N‐type negative resistance. The device consists of a low responsivity GaAs/AlAs multiple quantum well modulator on top of a GaAlAs photodetector. The structure has a larger

Shaping of 1.9 ns laser pulses and optical switching behaviour with about 100 ps switching on/off times are measured in a bulk n-GaAs Fabry-Perot etalon. The etalon structure is not optimised, having a finesse of about 4 at low incident power. The im

Measurements have been made at wavelengths between 1486 and 1600 nm of nonlinear refraction and absorption in an InGaAs single quantum well centered in an InGaAsP waveguide. Band-edge resonant nonlinear refractive cross sections as large as σn = −

An all-epitaxial GaAs/GaAlAs optically bistable Fabry-Perot etalon, designed to maximise the band-edge resonant electronic nonlinearity relative to unwanted thermal effects, has been demonstrated to be capable of being held CW in either of the bistab

Methods are described for the calculation of the elastic and plastic properties of textured polycrystalline metals. The calculations involve the crystallite orientation distribution function derived from X-ray texture data together with data which de
