160 nm continuous tuning of an MQW laser in an external cavity across the entire 1.3 mu m communications window

摘要

A tuning range of 160 nm has been demonstrated with an InGaAsP/InP MQW laser in a grating extended cavity across the 1.3 mu m optical fibre communications window. The device tuned continuously from 1.255 mu m to 1.417 mu m with a CW power output of over 40 mW at 1.336 mu m.
