Abstract: An optical circuit includes solid state photonics. The optical circuit includes a phased array of solid state waveguides that perform beamsteering on an optical signal. The optical circuit includes a modulator to modulate a bit sequence onto the carrier frequency of the optical signal, and the beamsteered signal includes the modulated bit sequence. The optical circuit includes a photodetector to detect a reflection of the beamsteered optical signal. The optical circuit autocorrelates the reflection signal with the bit sequence to generate a processed signal.

Abstract: Embodiments herein relate to a photonic integrated circuit (PIC) with an on-chip optical isolator. The PIC may comprise a laser, a waveguide coupled with the laser, and a closed loop resonator coupled to the laser through the waveguide. A magneto-optical (MO) layer is over and in contact with the waveguide and the closed loop resonator. The closed loop resonator may comprise a first polarization rotator (PR) and a second PR. A light from the laser in transverse electric (TE) mode through the waveguide is rotated in the first PR to a light in transverse magnetic (TM) mode, and the light in TM mode is rotated in the second PR to light in TE mode. The isolator may further comprise a micro-heater over or along a side of the waveguide and separated from the closed loop resonator; and a feedback control loop connected to the closed loop resonator and the micro-heater.

Abstract: Embodiments of the present disclosure are directed towards a micro-electromechanical system (MEMS) sensing device, including a laser arrangement configured to generate a light beam, a first waveguide configured to receive and output a first portion of the light beam, and a second waveguide having a section that is evanescently coupled to the first waveguide and configured to receive and output a second portion of the light beam. The section of the second waveguide is configured to be movable substantially parallel to the first waveguide, wherein a movement of the section of the second waveguide may be caused by an inertial change applied to the sensing device. The movement of the section may cause a detectable change in light intensity between the first and second portions of the light beam. Based on the detected change, the inertial change may be determined. Other embodiments may be described and/or claimed.

Abstract: Embodiments of the present disclosure are directed towards techniques and configurations for MEMS sensing device configured to determine inertial change applied to the device. In one instance, the device may comprise a laser arrangement configured to generate a light beam, and a waveguide configured to split the light beam into two portions. The waveguide may include two arms through which the respective portions of the light beam may respectively pass, and disposed substantially parallel with each other and joined together around their respective ends to recombine the portions into a light beam. One of the arms may be deformable. A deformation of the arm may result in a change of an optical path length of a portion of the light beam traveling through the arm, causing a detectable change in light intensity of the recombined light beam outputted by the waveguide. Other embodiments may be described and/or claimed.
