Abstract: Embodiments may relate to a silicon photonic chip, and particularly a back absorber within the silicon photonic chip. The back absorber may include a substrate material with a slab portion that includes a doped portion of the substrate material. The back absorber may be positioned at the backside of a laser that is configured to project light along a waveguide of the silicon photonic chip. Other embodiments may be described or claimed.

Abstract: Embodiments of the present disclosure may relate to a digitized grating that may include a first unit cell that has a first period and a first length, where the first period includes a first grating element width and a first space between adjacent grating elements, and where the first length includes a number of first periods. The digitized grating may further include a second unit cell that has a second period and a second length, where the second period is different than the first period and includes a second grating element width and a second space between adjacent grating elements, and where the second length includes a number of second periods.

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: Described are embodiments of hybrid optical apparatuses including anti-resonant optical waveguides, and methods for making such apparatuses and systems. In one embodiment, a hybrid optical apparatus may include a first semiconductor region including an active region of one or more layers of semiconductor materials and a second semiconductor region coupled with the first semiconductor region. The second semiconductor region may include an optical waveguide configured to transmit light inputted by a light input component. The optical waveguide may be defined by a first trench disposed on a first side of the waveguide, and a second trench disposed on a second side of the waveguide opposite the first side. A width of each trench may vary along a length of the apparatus to control optical power density of the light transmitted along the optical waveguide. Other embodiments may be described and/or claimed.

Abstract: In one embodiment of a superluminescent diode, a first diode adapted on a semiconductor die is to be forward-biased to output optical energy in response to a bias signal, and a second diode adapted on the semiconductor die is to be reverse-biased, the second diode to receive and absorb back propagating optical energy from the first diode and output a measure of the back propagating optical energy as an absorber feedback current. A comparator may be configured to compare the absorber feedback current to a reference current and output a comparison signal, and a driver control circuit coupled to the comparator may provide the bias signal based at least in part on the comparison signal. Other embodiments are described and claimed.
