Abstract
Tapered semiconductor lasers are a cost-effective solution to achieve the high brightness required by a large number of applications. These devices consist of two coupled sections: a ridge waveguide (RW) section, and an index or gain guided tapered section. The use of two electrically isolated RW and tapered sections, with separate control of the injected current to each section, adds a new degree of freedom to increase the brightness, and opens new applications requiring the modulation of a high optical power. An improvement of the device performance by stronger pumping of the RW section has been reported [1], In this work we present simulations of the operation of tapered lasers with separate contacts, in comparison with the experimental results, with the goal of providing a physical understanding of the origin of this improvement.
