A newly developed stripe-geometry injection laser is presented with built-in passive waveguiding produced by an effective refractive-index step between active stripe and adjoining regions. In contrast with the similar CSP laser, however, confinement of the lasing mode is achieved by metal reflection instead of excess absorption loss outside the active stripe. A model for this type of injection laser is established, and a numerical analysis of the waveguiding mechanism is performed. As a result, design curves are obtained that directly determine the technological parameters required for diode preparation.
