Abstract
A novel laser diode, in which the pumping area is increased by a multi -mode interference (MMI) coupler, is proposed to maintain single-lobe outputs up to high powers. Utilising active 1x1 MMI couplers between s inglemode waveguides, up to 90% higher single-lobe and fibre-coupled o utput powers were obtained at 1.3 mu m.
