Control of evanescent wave coupling in hybrid III–V/SOI nanolaser

Silicon photonics, enhanced by III-V semiconductors based optical functions, is one of the most promising technologies to achieve large-scale photonic integration taking advantage of the best of both materials. In this work, we study III-V/SOI hybrid structures that combine photonic crystal nanolasers with photonic wires. This approach is particularly interesting as it enables the achievement of compact devices (footprint as small as 5μm²) with low power activation and ultrafast response.
