All-Optical Beam Steering Using the Polariton Lighthouse Effect
نویسندگان
چکیده
We demonstrate theoretically and experimentally that a specifically designed microcavity driven in the optical parametric oscillation regime exhibits lighthouse-like emission, is, an emission focused around single direction. Remarkably, direction of this microlighthouse is continuously controlled by linear polarization incident laser, angular beam steering over 360° demonstrated. Theoretically, effect arises from interplay between nonlinear response exciton–polaritons, difference subcavities forming microcavity, rotational invariance device.

Demonstration of all-optical beam steering in modulated photonic lattices.
We demonstrate experimentally all-optical beam steering in modulated photonic lattices induced optically by three-beam interference in a biased photorefractive crystal. We identify and characterize the key physical parameters governing the beam steering and show that the spatial resolution can be enhanced by the additional effect of nonlinear beam self-localization.
متن کاملOptical Phased Array Using High-Contrast Grating All-Pass Filters for Fast Beam Steering
A novel 8x8 optical phased array based on high-contrast grating (HCG) all-pass filters (APFs) is experimentally demonstrated with high speed beam steering. Highly efficient phase tuning is achieved by micro-electro-mechanical actuation of the HCG to tune the cavity length of the APFs. Using APF phase-shifters allows a large phase shift with an actuation range of only tens of nanometers. The ult...
متن کاملHigh-resolution beam steering using microlens arrays.
Imaging or beam-steering systems employing a periodic array of microlenses or micromirrors suffer from diffraction problems resulting from the destructive interference of the beam segments produced by the array. Simple formulas are derived for beam steering with segmented apertures that do not suffer from diffraction problems because of the introduction of a moving linear phase shifter such as ...
متن کاملLiquid Crystal Optical Phase Modulators for Beam Steering
Beamsteering using liquid crystals can be achieved with refractive or diffractive implementations. The common thread in these various structures is that the liquid crystal is employed as an optical phase modulator. Either nematic or smectic liquid crystal phases can be used to shift the phase of light and steer an optical beam. Various liquid crystal optical phase modulating schemes will be des...
متن کاملOptical phased-array beam steering controlled by wavelength.
A scheme for optical phased-array beam steering controlled by wavelength is proposed. In this scheme, the optical scanning device consists of arrayed optical waveguides with specific length differences, by which the desired phase slope that results in optical beam steering is formed at the ends of the waveguides and can be changed by varying the optical wavelength. By introducing the concept of...
