Abstract

Photonic integration of visible ultra-narrow tunable laser sources has great potential for a wide range of applications, including atomic clocks, and quantum sensing. The two opposing approaches are extended cavity diode lasers (ECDLs) or self-injection locking (SIL), e.g., of Fabry-Perot diode lasers [1]. Typically, ECDLs are preferred for wide tunability [2], while the narrowest linewidths have been achieved by self-injection locking [3] in the infrared.
