Thermal management of a ridge-type hybrid laser, device, and method

摘要

Aspects and embodiments relate to a device and method for providing a device. The device comprises: a ridge-type hybrid laser; and a thermally conductive, electrically insulating, coating adjacent a surface of the ridge-type hybrid laser; the coating being configured to transfer heat away from the laser. It will be appreciated that aspects and embodiments recognise that a thermal solution can be implemented to enable energy efficient, scalable, reliable and low cost cooling designs for integrated photonics devices. An arrangement in accordance with aspects and embodiments described herein can provide improved thermal performance of a hybrid ridge type laser device. Such improved thermal performance can facilitate better temperature control, and lower device temperature can result in better device performance and longer device lifetimes. Aspects and embodiments help to provide an integrated thermal approach which can deal with thermal spreading close to where heat on a device is generated within a laser waveguide.
