Abstract
We present an InP-based laser with Y-coupling [1] inspired resonator cavity. This design allows the reduction of gain-saturation and two-photon absorption [2]. This is achieved by increasing the cross-section of laser mode (reducing the field intensity) while maintaining single spatial mode operation, which is very important in numerous semiconductor laser applications. This design can be applied to wide-waveguide lasers [3], as in this work, as well as to SCOWL (slab-coupled optical waveguide laser) [4].
