Abstract: Embodiments of the present disclosure are directed to a silicon photonics integrated apparatus that includes an input to receive an optical signal, a splitter optically coupled to the input to split the optical signal at a first path and a second path, a polarization beam splitter and rotator (PBSR) optically coupled with the first path or the second path, and a semiconductor optical amplifier (SOA) optically coupled with the first path or the second path and disposed between the splitter and the PBSR. Other embodiments may be described and/or claimed.

Abstract: In one embodiment, an apparatus comprises: a coherent optical receiver front-end circuit to receive an optical signal comprising information and further to receive a local oscillator optical signal, and output an orthogonal electrical signal based on the optical signal; a processing circuit coupled to the coherent optical receiver front-end circuit to receive the orthogonal electrical signal and process the orthogonal electrical signal to generate therefrom sum of squares information; and a non-coherent receiver coupled to the processing circuit to recover the information from the sum of squares information. Other embodiments are described and claimed.

Abstract: Techniques for termination for microring modulators are disclosed. In the illustrative embodiment, a microring modulator on a photonic integrated circuit (PIC) die is modulated by radiofrequency (RF) signals connected to electrodes across the microring modulator. A resistor is connected to each of the electrodes. The resistors both provide termination for the RF signals, preventing or reducing reflections, as well as forming part of a bias tee, allowing for a DC bias voltage to be applied across the electrodes.

Abstract: Filter circuitry is provided for use with a light detection and ranging (Lidar) device implemented using silicon photonics. The filter circuitry includes high-pass filter circuitry to receive a signal from a photodetector of the lidar device and attenuate a lower frequency portion of the signal, where the lower frequency portion of the signal is the result of optical back reflections within the lidar device.
