Abstract: A connector is disclosed that includes a housing and first and second attachment areas located in the housing and spaced apart from each other along the mating direction of the connector. The second, but not the first, attachment area is designed to move relative to the housing. The connector further includes an optical waveguide that is permanently attached to, and under a first bending force between, the first and second attachment areas. The connector also includes a light coupling unit located in the housing for receiving light from the optical waveguide and transmitting the received light to a mating connector along a direction different than the mating direction of the connector. The mating of the connector to the mating connector causes the optical waveguide to be under a greater second bending force between the first and second attachment areas.

Abstract: Novel small-footprint integrated photonics optical gyroscopes disclosed herein can provide ARW in the range of 0.05°/?Hr or below (e.g. as low as 0.02°/?Hr), which makes them comparable to fiber optic gyroscopes (FOGs) in terms of performance, at a much lower cost. The low bias stability value in the integrated photonics optical gyroscope corresponds to a low bias estimation error (in the range of 1.5°/Hr or even lower) that is crucial for safety-critical applications, such as calculating heading for autonomous vehicles, drones, aircrafts etc. The integrated photonics optical gyroscopes may be co-packaged with mechanical gyroscopes into a hybrid inertial measurement unit (IMU) to provide high-precision angular measurement for one or more axes.

Abstract: Disclosed is a system for arbitrary control of amplitude, phase and polarization characteristics of light in pulsed laser systems, allowing fast pulse-to-pulse modification of the above-mentioned parameters for single pulses or arbitrarily long and closely-spaced bursts of pulses. The control uses an electro-optic device, driving it by a specially designed high voltage driver. The operation of the driving electronics is based on the precise control of charging and discharging a Pockels cell inherent capacitance. This inherent capacitance is typically considered as parasitic. Therefore, prior voltage drivers operate in spite of the capacitance instead of using it. The present high voltage driver consists of a multitude of current-controlled stages capable of sinking and sourcing specific and adjustable currents into the capacitive load of the Pockels cell. The disclosed device and the corresponding control method allow for precise and energy-efficient shaping of Pockels cell control voltage.
