    Abstract: Examples include hybrid silicon photonic device structures. Some examples include a method of integrating a photodetector with a photonic device on a silicon wafer to make a hybrid silicon photonic device structure. A dielectric layer is established on the silicon wafer. A pit is formed in a portion of the dielectric layer and the silicon wafer, wherein a bottom of the pit is silicon. A germanium layer is grown in the pit such that a top of the germanium layer is lower than a top of the silicon wafer. The germanium layer comprises the photodetector. A photonic device material that comprises the photonic device is bonded to the silicon wafer without planarization of the silicon wafer.

    Abstract: One example includes an optical fiber interface. The interface includes a first substrate comprising a pair of opposing surfaces. The substrate includes an opening extending therethrough that defines an inner periphery. One surface of the opposing surfaces of the first substrate can be configured to be bonded to a given surface of a second substrate. The interface also includes a plurality of optical fibers secured to the other opposing surface of the first substrate and extending inwardly from a plurality of surfaces of the inner periphery at fixed locations to align the set of optical fibers to optical inputs/outputs (I/O) of an optical system chip that is coupled to the given surface of the second substrate and received through the opening.

    Abstract: One example includes an optical transmitter system. The system includes a waveguide to receive and propagate an optical signal. The system also includes a ring modulation system comprising a ring resonator that is optically coupled to the waveguide and is to resonate a given wavelength of the optical signal in response to an input data signal that is provided to a modulation amplifier to provide carrier injection to change a refractive index of the ring resonator to resonate the given wavelength of the optical signal to modulate the optical signal. The system further includes a tuning controller associated with the ring modulation system. The tuning controller can implement iterative feedback tuning of the ring modulation system based on a relative amplitude of an optical intensity of the given wavelength in the ring resonator and a variable reference amplitude to substantially stabilize the ring resonator with respect to the given wavelength.

    Abstract: In one example, a device includes a photodetector to generate an electrical signal in response to an optical signal and a transimpedance amplifier unit to receive the electrical signal. In one example, the transimpedance amplifier unit may include a first inverter unit, a second inverter unit coupled to the first inverter unit, and a third inverter unit coupled to the second inverter unit. In one example the third inverter unit may include a feedback resistor and a first n-type transistor in parallel to the feedback resistor, where the first n-type transistor is to provide a variable gain of the third inverter unit.
