Abstract:

This report results from a contract tasking University College London as follows The objective of the tasking was to realize GaAsAlGaAs tunable lasers which use the quantum-confined Stark effect QCSE as a tuning mechanism to produce a uniform frequency modulation FM response. A detailed analysis of optical frequency modulation analogue link is presented. It is shown that these enable non-linear limits on the dynamic range of long 100km links to be overcome. Using realistic system parameters signal to noise ratios exceeding 156 dB. Hz are predicted for 1000km links.
