Patents by Inventor Lionel You Liang Wong

Lionel You Liang Wong has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Optical device, gas sensor, methods of forming and operating the same
    Patent number: 11385421
    Abstract: Various embodiments may relate to an optical device. The device may include an elongate substrate, an emitter portion at a distal end portion of the elongate substrate, the emitter portion configured to emit light, and an actuator portion at a proximal end portion of the elongate substrate opposite the distal end portion of the elongate substrate. The emitter portion may include a first electrode, a second electrode, and an active layer between the first electrode and the second electrode so that the light is emitted due to an increase in a temperature of the active layer upon application of a first potential difference between the first electrode and the second electrode. The active layer may be patterned to form a photonic crystal layer for enhancing directionality of the emitted light.
