Thermally stable integrated laser
One problem in silicon photonics is that current integrated light sources are very sensitive to variations in the operating temperature.
Together with the Centre for Advanced Photonics & Process Analysis we have developed a hybrid laser with an external reflector based on silicon nitride gratings. The silicon nitride grating has a low thermo-optic coefficient and so our laser can operate unaffected over a large temperature range.
Our laser has a low threshold power, provides mW level output power and shows stable operation over a wide temperature range.
