Abstract:
A semiconductor device comprising a substrate; a monolithic gain region disposed on the substrate and operable to produce optical gain in response to current injection, including a first electrode over a first portion of the gain region having a first length L1, with a first current I1 being applied; and a second electrode over a second portion of the gain region having a second length L2, with a second current I2 being applied; wherein I1/L1 is greater than I2/L2.
