Measurement

The Group has a suite of laboratories containing state-of-the-art processing and test equipment. The Telecommunications Systems Laboratories house amplified in-line and recirculating loop testbeds operating at very high data rates (>80 Gb/s) with Bit Error Rate test capability and WDM. The Group operates 4 CW/pulsed UV laser grating inscription systems for fibre and planar device fabrication, as well as an amplified femtosecond pulse (3 mJ) Ti:sapphire system for advanced fabrication studies. A Class 1000 facility clean room has recently been constructed and equipped for planar device fabrication
