ABSTRACT:
A two part semiconducting laser having a gain part including a junction and a relatively thin phase part. A partially reflective mirror is on the exterior of the phase part. The junction voltage is sensed and processed to obtain a control signal that is applied to the phase part to control the reflectivity of the mirror, in order to reduce the linewidth to below the Henry linewidth and down to the ST limit.
