摘要： An optical phase shifter array includes: 1st˜nth optical-splitting elements, wherein each has an input end, a first output end and a second output end, and the input end of the 1st optical-splitting element receives an input light and outputs an evenly distributed optical signal to the optical-splitting element of the next stage, and n is a positive integer above 1; a plurality of first optical waveguides respectively connected to the input end of the optical-splitting element of the odd-numbered column of the next stage and the first output end of the optical-splitting element of the previous stage; a plurality of second optical waveguides respectively connected to the input end of the optical-splitting-element of the even-numbered column of the previous stage; and phase shifters of the 1st to the kth stage, which makes the optical signal passing through the optical waveguides produce a phase shift by heating or electro-optic effects.

摘要： A method includes generating a mixed optical beam using an optical phased array that includes multiple array elements, where each array element includes an antenna element and a phase modulator. The mixed optical beam includes a combination of (i) an output optical beam produced by the optical phased array and (ii) a reference optical beam. The method also includes capturing near-field measurements of the mixed optical beam, where the near-field measurements are captured while scanning phase angles of the phase modulators. The method further includes generating calibration data based on the near-field measurements, where the calibration data identifies phase and amplitude responses of the array elements. In addition, the method includes storing the calibration data.

摘要： An interferometer comprises a plurality of waveguide branches comprising a plurality of bus waveguides and a plurality of photonic resonators. A first waveguide branch of the plurality of waveguide branches comprises a first photonic resonator coupled to a first bus waveguide. The first photonic resonator is disposed to couple and circle a first portion of an optical beam at the first photonic resonator to generate a first phase shift of the first portion of the optical beam, where the first phase shift is the same as a second phase shift of a second photonic resonator coupled to a second bus waveguide.

摘要： An electrical-optical modulator may include one or more optical waveguides to propagate one or more optical signals in a direction of propagation. An optical waveguide of the one or more optical waveguides may include a time delay section, a first modulation section preceding the time delay section in the direction of propagation, and a second modulation section following the time delay section in the direction of propagation. The first modulation section and the second modulation section may be configured to be associated with opposite modulation polarities, and the time delay section may be configured to delay a phase of the one more optical signals relative to the first modulation section. The electrical-optical modulator may include one or more signal electrodes to propagate one or more signals in the direction of propagation in order to modulate the one or more optical signals through electrical-optical interaction.

摘要： An infant care device that can include a failure indicating feature in one or more of the side panels to discourage improper use of the side panels to move the infant care device. When a side panels is used to move the infant care device and a force greater than a pre-determined maximum is applied to the side panel, the failure indicting feature indicates such improper use. The failure indicating feature is designed to provide an indication at a level of force that is less than the level of force that would damage the hinge and latch assembly holding the side panel. The failure indicating feature can provide a physical indication or a visual indication when a force greater than a predetermined maximum is applied to the side panel.
