Abstract: Semiconductor lasers offering kilohertz intrinsic linewidths in the C-band are indispensable for space coherent optical communications. However, conventional Fabry-Pérot external-cavity lasers (FP-ECLs) offer only modest mode-hop-free tuning, thereby limiting Doppler shift compensation. Here, we demonstrate… read more here.
