An optimised ultra-low power thermo-optic waveguide switch design is presented.

We report travelling wave 1.5micron semiconductor laser amplifiers with very low gain ripple. The average facet reflectivity is less than 5 x 10 sup -5 over a 170 angstrom interval.

The newly-discovered even-denominator fractional quantum Hall effect (FQHE) at filling factor nu =5/2 has been studied at ultra-low temperatures.

We present experimental data showing unambiguously an even-denominator fractional quantum Hall effect (FQHE) state at nu=5/2.

The performance of four low power X-band low-noise amplifier (LNA) topologies implemented in a 0.18 um SiGe BiCMOS technology is compared.

A new design has been used for cooling GaAs/AlxGa1-xAs sample to ultra-low-temperatures.

We describe a head-stage, with precision microtranslators for the chronic placement of micro-wire electrodes in the neocortex, that minimizes compressive damage to the brain.

Monolithic quantum dot Fabry-Perot laser diodes are fabricated and characterized for ultra-stable clock signal generation.

The focus of this paper on mission-critical communications in a 5G cellular communication system.

We investigate the potential of different diversity and interference management techniques to achieve the required downlink SINR outage probability for ultra-reliable communications.
