Summary :

Generating mechanism of excess noise in semiconductor lasers induced by optical feedback is theoretically analyzed and experimentally examined. In case that the reflecting point is relatively far from the laser, noise gradually increases due to growing up of the external cavity modes with increasing of optical feedback. When the reflecting point is near, the lasing operation turns into unstable state abruptly with relatively large amount of feedback without showing the gradual increase of noise.
