Abstract
Theoretical analysis of complex-coupled, surface-emitting distributed feedback (CC-SE-DFB) diode lasers with distributed Bragg reflectors (DBR) is presented. These devices are shown to produce symmetric-mode (single-lobe) surface emission with high efficiency (30%) and uniform near-field in the longitudinal direction. High efficiency and uniform near-field are both necessary for achieving high powers in a single-lobed beam. It is also shown that the device studied here may be combined with a Resonant Optical Waveguide array device which has a uniform near-field in the lateral direction to achieve a two-dimensional surface-emitting device capable of providing greater than 1W CW power in a stable, single-lobed beam.
