Abstract
In some embodiments, a photonic device includes a photonic interconnect structure that includes a first cladding layer; a waveguide over the first cladding layer; a second cladding layer disposed over the waveguide; a transparent material in the first cladding layer and the second cladding layer, the transparent material includes a first sidewall adjacent to the waveguide and a second sidewall tilted with respect to the first sidewall of the transparent material; and a first reflective film over the second sidewall of the transparent material. In some embodiments, the photonic device also includes a light-receiving structure that includes a transparent protrusion above the transparent material, the transparent protrusion including a first sidewall and a second sidewall opposite to the second sidewall of the transparent protrusion; and a second reflective film over the second sidewall of the transparent protrusion and horizontally overlapping the first reflective film.
