Abstract
Systems and methods according to the present invention address this need and others by providing SLD devices and methods for generating optical energy that reduce internal reflections without the use of an absorber region. This can be accomplished by, among other things, adapting the waveguide geometry to dump reflections from the front facet out through the back facet of the device.
