Abstract
There is disclosed in one example a fiberoptic communication device, including: a modulator to modulate data onto a laser pulse; and a semiconductor laser source including an active optical waveguide to provide optical gain and support an optical mode, the laser source further including a V-shaped current channel superimposed on the optical waveguide, and disposed to feed the active optical waveguide with electrical current along its length, the current channel having a proximate end to the optical mode, the proximate end having a width substantially matching a diameter of the optical mode, and a removed end from the optical mode, wherein the removed end is substantially wider than the proximate end.
