  • Patent number: 11448815
    Abstract: A compact collimator or projector includes a waveguide having a slab core structure supporting at least two lateral modes of propagation. A light beam coupled into a first mode propagates to an edge of the waveguide where it is reflected by a reflector to propagate back. Upon propagation back and forth, the light is converted into a second mode. An out-coupling region, such as an evanescent coupler, is provided to out-couple the light propagating in the second mode. The reflector may have focusing power to collimate the out-coupled light beam. The light beam may be converted from the first to the second mode without being reflected from a reflector.

  • Patent number: 11409048
    Abstract: A tunable wavelength filtering device is presented in which the tuning mechanism is based on altering the incident angle to an optical thin film coating stack, or thin film optical filter. Rotating mirrors, such as Micro-Electro-Mechanical Systems (MEMS) tilt-mirrors, are used to alter the incident angle of the optical beam coming from an input fiber, and also to aim or align the exiting beam to an output optical fiber. The optical thin film coating stack can be implemented onto a glass substrate, to form a thin film filter chip. The thin film filter chip can be fixed in place, and the incident angle and exiting angle of the optical beam is varied by adjusting the tilt angle of the two rotating mirrors.

  • Patent number: 11333826
    Abstract: A silicon- and optical phased array-based integrated optically adjustable delay line, comprising, an optical phased array transmitting unit, a slab waveguide transmitting unit, and an optical phased array receiving unit that are sequentially arranged. By the optical phase control transmitting unit, the phase difference between channels is regulated and controlled via a phase shifter to change a far-field interference light spot and form a wave beam with directivity to regulate and control an incident angle of an optical signal entering the slab waveguide, thus changing the propagation path length of the optical signal. Finally, the optical signal is received by a corresponding optical phased array receiving unit to obtain different delay amounts. Large adjustable delay amount is realized and the delay line has the advantages of simple structure and control and high integration level with high application value in optical communication and microwave photonic and optical signal processing.

  • Patent number: 11314024
    Abstract: A fiber optic connector deploys a latch lever release with an elastic rib. When the latch lever release is depressed down or toward the optical axis of the connector, a hook seated within a recess of the connector outer housing, the hook is lifted out of the recess thereby allowing the connector to be removed from the adapter port. A pivot point is formed between the main body of the latch lever release and the connector outer housing. Depressing the latch lever release distal of the pivot point at the trigger portion displaces the hook from the connector thereby allowing the user to remove the connector from a receptacle port, such as an adapter port.
