An optoelectronic device and method of manufacturing the same. The device includes: a layer disposed above a substrate, the layer having a first cavity therein, which cavity is at least partially defined by an inclined interface between the cavity and an insulating liner, the interface being disposed at an angle relative to the substrate of greater than 0&#xb0; and less than or equal to 90&#xb0;; and a regrown semiconductor material, providing or forming a part of a waveguide, the regrown semiconductor material being at least partly disposed in the first cavity and including an inclined interface between the regrown semiconductor material and the insulating liner, the interface being disposed at an angle relative to the substrate of greater than 0&#xb0; and less than or equal to 90&#xb0;.
