Paper Abstract

We present a multi-trench channel waveguide design that supports a single-guided mode with large-mode area. Geometrically shaped waveguide with suitable design parameters ensure effective single-mode operation by introducing high leakage loss to higher-order modes while a nominal loss to the fundamental mode. A waveguide of ~ 2.2 mm length is able to ensure single-mode operation with the core area of 100 μm2. Such a large confinement area for mode propagation can effectively suppress nonlinear optical effects. The proposed channel waveguide structure is expected to find applications in high power devices and components such as high power waveguide lasers, amplifiers and sensors.
