Abstract: Embodiments described herein may be related to apparatuses, processes, and techniques related to coherent optical receivers, including coherent receivers with integrated all-silicon waveguide photodetectors and tunable local oscillators implemented within CMOS technology. Embodiments are also directed to tunable silicon hybrid lasers with integrated temperature sensors to control wavelength. Embodiments are also directed to post-process phase correction of optical hybrid and nested I/Q modulators. Embodiments are also directed to demultiplexing photodetectors based on multiple microrings. In embodiments, all components may be implements on a silicon substrate. Other embodiments may be described and/or claimed.

Abstract: Embodiments of the present disclosure are directed to multi-wavelength laser generator may produce light with a frequency comb having equally spaced frequency lines. In various embodiments, the laser generator includes first, a semiconductor gain element is used to provide gain to the laser being generated. Second, a ring resonator filter, or ring filter, is used to select the wavelength comb spacing. Third, a narrow-band DBR or narrow-band mirror is used to select the number of wavelengths that lase. Fourth, a wide-band or narrow-band mirror is used to provide optical feedback and to form the optical cavity. Fifth, a phase tuner section is used to align the cavity modes with the ring resonances (i.e. the ring filter modes) in order to reduce or minimize the modal loss. Other embodiments may be described and/or claimed.

Abstract: Embodiments include apparatuses, methods, and systems including a semiconductor photonic device having a waveguide disposed above a substrate. The waveguide has a first section including amorphous silicon with a first refractive index, and a second section including crystalline silicon with a second refractive index different from the first refractive index. The semiconductor photonic device further includes a heat element at a vicinity of the first section of the waveguide. The heat element is arranged to generate heat to transform the amorphous silicon of the first section of the waveguide to partially or completely crystallized crystalline silicon with a third refractive index. The amorphous silicon in the first section may be formed with silicon lattice defects caused by an element implanted into the first section. Other embodiments may also be described and claimed.
