Placement at Oclaro

Lastly i have managed to get to Caswell where a company called Oclaro is based. i will be here for 3 months working placement. I will be working on Mach-Zehnder modulators..trying to figure out ways to reduce/eliminate one of the problematic characteristics affecting the devices. This menace is called frequency Chirp...it is caused by light carrying a signal travelling at different speed in the optical fiber such that the trailing edge arrive earlier or later than expected. This causes the signal to degenerate and limit transmission distance before you need a repeater...so that is the challenge.
