Self-oscillations of V-channeled substrate inner stripe (VSIS) lasers with index guiding and the influence of external feedback on low-frequency noise generation are presented. The self-oscillation is induced by means of shortening a cavity length of VSIS laser to 110 ..mu..m. VSIS lasers with self-oscillation have the fundamental linewidth of 0.56 A below 3 mW and are not sensitive to both phase and amplitude of the externally reflected light. Signal to noise ratio of short-cavity VSIS laser at 1 MHz with a 10-KHz bandwidth was 97 dB at 0.05% optical feedback.
