Coupling light from an optical fibre to small optical waveguides is particularly problematic in semiconductors, since the refractive index of the silica fibre is very different from that of a semiconductor waveguide. There have been several published

The recent interest in silicon based photonics, and the trend to reduced device dimensions in photonic circuits generally, has led to the need for mode converters to couple from optical fibres to such small devices. A range of structures have been pr

Recently there has been a strong trend to fabricate smaller photonic devices. In the literature, the problem of coupling optical fibres with thin semiconductor waveguides has not been solved sufficiently well to obtain both high coupling efficiency a

A simple valveless micropimp is fabricated using optical lithography and copper electroplating. The micropump is activated by magnetic force produced by two opposite spiral flat coils. Each coil consists of 30 tracks with 6mm diameter and 320m2 cross

Silicon-on-insulator (SOI) technology offers tremendous potential for the integration of optoelectronic functions on a silicon substrate. In this research, we report on the fabrication process of a Mach-Zehnder interferometer on an SOI with 0.5μm wi
