Spectroscopic methods involving the sudden injection or ejection of electrons in materials are a powerful probe of electronic structure and interactions.

Optical four-wave mixing resonances in sodium vapor induced by collisions with invert buffer gases (He,Ar,Xe,N2) are characterized at high resolution (5 MHz) using lasers tuned near the D-lines

We describe a transfer printing technique for directly patterning thin gold films onto GaAs surfaces.

A three-crystal geometry has been used for high-resolution X-Ray Diffraction (XRD) along with lattice imaging Transmission Electron Microscopy (TEM) to study two high-quality InGaAs/InP multi-quant

High resolution X-ray diffraction (HRXRD) studies have been carried out to determine the structural perfection and periodicity for a number of high-quality InGaAs/InP superlattices and one InGaAsP/

Evanescently-coupled avalanche photodiodes utilising a planar short multimode waveguide are demonstrated.

We demonstrate a high-sensitivity broadband micro-Michelson fiber interferometer using a singlemode fiber end-spliced with a short (43.9μm) hollow-core end-collapsed lensed fiber.

A practical and sensitive sampling setup based on linear interference of the waveform under test with a sampling pulse combined with a waveguide optical hybrid demonstrates quasi-distortion-free sa

A practical sampling setup based on linear interference of an optical signal with a sampling pulse in a waveguide optical hybrid demonstrates record-sensitivity sampling of eye diagrams up to 640 G

A high-input-sensitivity decision D flip-flop integrated circuit was designed and fabricated in a self-aligned InP double heterojunction bipolar transistor technology (F/sub t/=180 GHz, F/sub max/=
