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.
