Abstract
A photonic device and related method for forming a photonic device. In some embodiments, a method of fabricating a photonic device includes forming a layer stack over a substrate. In some cases, the layer stack includes a lower cladding layer, a core layer disposed over the lower cladding layer, and an upper cladding layer disposed over the core layer. In some examples, the method further includes patterning the layer stack to form a waveguide for the photonic device. In some cases, the waveguide includes the core layer, and the core layer includes a lateral surface having a convex profile.
