Abstract
A photonic integrated circuit structure includes a semiconductor substrate. A waveguide is disposed above the semiconductor substrate and has an inclined plane. A mirror coating layer is conformally disposed on the inclined plane. A cladding layer covers the waveguide and the mirror coating layer. A hole is disposed in the semiconductor substrate or the cladding layer, and the hole overlaps the inclined plane in a vertical direction. In addition, an optical fiber is disposed in the hole to receive a reflected light from the mirror coating layer.
