Title:
THERMAL COMPENSATION FOR BURST-MODE LASER WAVELENGTH DRIFT
Document Type and Number:
WIPO Patent Application WO/2016/054981
Kind Code:
A1
Abstract:
An apparatus comprising a burst-mode laser(610) comprising an active layer(720) and configured to emit an optical signal during a burst period, wherein a temperature change of the burst-mode laser(610) causes the optical signal to shift in wavelength, and a heater(620) thermally coupled to the active layer(720) and configured to reduce a wavelength shift of the optical signal during the burst period by applying heat to the active layer(720) based on timing of the burst period.
