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.
