Abstract

It is well known that quiet current pumping in semiconductor lasers can give rise to good noise characteristics. This is achieved by use of a driving circuit with a high internal impedance. An analysis of the amplitude noise behavior that occurs with varying the source resistance is carried out. In particular, it is pointed out that the driving resistance also affects the optical noise sources in a region of injection current that is not too far above threshold. Numerical results are presented for a post microcavity laser device.
