Abstract
High frequency (HF) modulation method is commonly used in magneto-optic (MO) disk drive to reduce the laser noise, which is mainly caused by optical feedback (OFB). In this paper, the noise behavior of three commercial laser diodes is studied, to find their optimum operating conditions. It shows that their optimum conditions are significantly different. In addition, two of them are very sensitive to temperature while the other one is not.
