The explosive advancement in the optical transmission in recent years has created an unlimited appetite for high speed, high capacity system.

Au/Pt/GaN Schottky diode rectifiers were fabricated with reverse breakdown voltage (V sub (RB)) up to 550 V on vertically depleting structures and >2000 V on lateral devices.

We describe a 64 × 43 Gb/s unrepeatered transmission experiment over 440 km of ultra-low loss fiber with third-order Raman pumping.

There has been considerable progress in the telecommunications technology based on the transmission of lightwaves through optical fibers.

This talk describes a broadband digital switch intended for future visual and data communication needs.

High-capacity, long-haul transmission over a coupled-core three-core multi-core fiber is investigated in a recirculating loop experiment.

IEEE We experimentally investigate high-capacity fewmode fiber transmission for short and medium-haul optical links.

The responsivity of polarization sensitive quantum well infrared photodetectors with small pixel size (down to 20Â μm) is investigated.

We have designed and performed the optical modeling of a cruciform cylindrical lens to replace the corrective lens in a confocal optical system and demonstrated a coupling efficiency of 85%. 

Melt-textured-growth of polycrystalline YBa sub 2 Cu sub 3 O sub (7-delta) superconductor using directional solidification created an essentially 100% dense structure consisting of long, needle- or
