LNOI external cavity laser with 25 Hz intrinsic linewidth
We present a hybrid LiNbO 3 -based integrated tunable external cavity laser (ECL) featuring a multi-period-delayed feedback photonics circuit. Compared to the MHz-level linewidth of a DFB-LD, the ECL achieves a significantly narrowed linewidth of 25 Hz.
