Abstract

Anti-phase-type complex-coupled, surface-emitting distributed feedback (CC-SE-DFB) diode lasers are analyzed for the first time. A metallic grating placed atop a semiconductor structure is shown to select lasing in the symmetric mode (i.e. orthonormal emission in a single-lobe pattern). The design utilizes a multi-quantum-well active region (emitting at 0.98 /spl mu/m), and a second-order metallic grating for both feedback and outcoupling mechanisms.
