Narnia is middleware that helps programmers build multimedia communication services.

A 27.88 three-pole 1.8% bandwidth silicon micro-machined filter with 50 dB rejection is presented.

We propose a new way of making highly resonant integrated optical circuits based on weak side-by-side coupling between waveguides and high Q distributed Bragg resonators.

We investigate narrow bandwidth filtering of 160 Gb/s signals with and without optical phase correlation between adjacent data pulses.

We investigate narrow bandwidth filtering of 160 Gb/s signals with and without optical phase correlation between adjacent data pulses.

The ability to create structures on length scales below 100 nm easily is a challenging feat.

A compact narrow linewidth semiconductor laser is described.

We have developed single frequency and single spatial mode laser structures with very narrow linewidth (~850 kHz @ 15 mW measured with an ECL).

We have developed single frequency (SMSR~50dB) and single spatial mode (M21.5) laser structures with stable narrow linewidth (1MHz) and high optical power (40mW), using an aluminium free active reg
