Influence of Injection–Current Noise on the Spectral Characteristics of Semiconductor Lasers
نویسندگان
چکیده
The spectral characteristics of a semiconductor laser are altered by injecting additional noise current into its currentdrive port. A continuously varying spectral linewidth from about 5 MHz to above 100 MHz is achieved experimentally in this semiconductor laser. The conditions under which the line shape changes from a standard Lorentzian shape to a Gaussian shape as functions of laser power and noise current are investigated and compared with an existing theoretical treatment.

متن کاملAmplitude noise reduction in semiconductor lasers with weak, dispersive optical feedback.
We present the theory and measurements of the amplitude noise spectrum from a semiconductor laser with weak optical feedback (P(fb)/P(out) approximately 10(-6)) from an external cavity containing an element of dispersive loss. The laser noise is found to be reduced over most of the low-frequency spectrum, although an increase in the noise is observed at frequencies corresponding to multiples of...
