OPTOELECTRONIC DEVICE INCORPORATING A TUNABLE LASER AND METHOD OF CHARACTERISATION THEREOF

摘要

A hybridised optoelectronic device (1) having a multi-section laser (100) and a wavelength measuring component (110) such that stable operational characteristics remote from mode boundaries (141, 142) may be determined and stored in a look-up table. A fast means of characterising the device using sampling techniques is also disclosed. The device may incorporate a frequency-locking component (120) to enable the laser to emit radiation at predetermined frequencies.
