Abstract
Injection lasers coupled to short passive resonators are known to affect the spectral properties of the devices.1 Tuning to different discrete wavelengths2 and suppression of side modes with current modulation have been reported.3 We have examined the effect of the length of the passive cavity on the temperature stability of planar-mirror short external resonator (SER) lasers with standard laser lengths (300 μm). We have found that thermal tuning of the external resonator length enhances the temperature stability for a wide range of external cavity lengths.
