Abstract:
Using flip-chip bonding, we demonstrate 70 kHz linewidth extended-cavity lasers emitting over 13 dBm waveguide power. The integration of an athermal control system allows for sub-minute laser calibration time, and under closed-loop control the laser’s frequency error is kept below 2.0 GHz across a 20 °C temperature range.
