ABSTRACT:
A channelled substrate diode laser in which transverse and longitudinal mode control is achieved by having the laser current profile flat over the substrate channel. A flat current profile over the substrate channel, which is achieved by having the width of the path of the pump current greater than the width of the channel, causes waveguiding to be influenced only by a fixed channel guiding factor.
