    Abstract: An optical switch includes a bus waveguide supported by a substrate, a coupling waveguide suspended over the bus waveguide, a reaction electrode coupled with, and adjacent to, the coupling waveguide, an actuation electrode supported by the substrate and configured to control a position of the coupling waveguide relative to the bus waveguide via the reaction electrode, and an optical antenna coupled with the coupling waveguide and disposed at a fixed distance from the bus waveguide. When a voltage difference between the reaction electrode and the actuation electrode is less than a lower threshold, the coupling waveguide is positioned a first distance from the bus waveguide, when the voltage difference between the reaction electrode and the actuation electrode is greater than an upper threshold, the coupling waveguide is positioned a second distance from the bus waveguide, and the second distance is less than the first distance.

    Abstract: A single chip LIDAR module includes a laser, a photo diode, a photonic integrated circuit (PIC), a lens, and a housing. The laser is configured to output light at a predetermined wavelength. The photo diode is configured to detect light energy at the predetermined wavelength. The PIC is coupled with the laser and photo diode, and is integrated with a MEMS switch array that includes an optical antenna configured to diffract light at the predetermined wavelength. The lens is arranged over the PIC. The housing is configured to encompass the laser, the photo diode, and the PIC, and having a window configured to pass light associated with the PIC.

    Abstract: An optical switch includes a bus waveguide supported by a substrate, an actuation electrode supported by the substrate, the actuation electrode having fins that protrude in a direction perpendicular to the substrate and to the bus waveguide, and a reaction electrode having interdigitated fins configured to form a comb drive with the actuation electrode. When a voltage difference between the reaction electrode and the actuation electrode is less than a lower threshold, the reaction electrode is positioned a first distance from the bus waveguide, when the voltage difference between the reaction electrode and the actuation electrode is greater than an upper threshold, the reaction electrode is positioned a second distance from the bus waveguide, and the second distance is less than the first distance.

    Abstract: An optical switch includes a first bus waveguide supported by a substrate, an optical antenna suspended over the first bus waveguide via a spring, and interdigitated electrodes coupling the substrate with optical antenna and configured to control a position of the optical antenna relative to the first bus waveguide. When a voltage difference applied to the interdigitated electrodes is less than a lower threshold, the optical antenna is at a first position offset from the first bus waveguide, when the voltage difference applied to the interdigitated electrodes is greater than an upper threshold, the optical antenna is at a second position offset from the first bus waveguide, and the offset at the second position is greater than at the first position.
