title: Strong discrimination of transverse modes in high-power laser diodes using Bragg channel waveguiding.
abstract: Three-dimensional waveguiding along the channel between two semi-infinite grating structures in a dielectric slab waveguide is suggested and analyzed using coupled-mode theory. In this type of waveguiding, a single transverse mode is possible even when the channel width is large, which is important for high-power laser-diode applications.
