Abstract :
Optical feedback effects on spectral properties of a semiconductor laser diode coupled to a single-mode fiber cavity are investigated. Linewidth reduction from 6 MHz to less than 30 kHz and frequency stability improvement with increasing feedback are reported. Experiments are in good agreement with theory for short fiber cavities.
