- Abstract
We demonstrate an ultra-fast athermal continuous wavelength-swept III-V-on-SOI MOSCAP DFB laser with a mode-hop-free-tuning up to 10 GHz in less than 2 ns. We also propose a new method to linearize the frequency response without any pre-distortion or active feedback in the gain’s current injection ramp. Instead, we polarize the III-V gain Section under direct current injection, and we drive the hybrid MOSCAP waveguide with an AC voltage signal. By optimizing its driving frequency, we demonstrate an ultra-fast athermal triangular-shaped time-varying frequency tuning with a speed of
