Two-Dimensional Optical Phased Array Reflector Based on Gires-Tournois Resonator
Optical phased array is a technical solution to realize non-mechanical beam steering in laser radar. In view of the large size and difficulty of two-dimensional integration of the existing optical phased arrays, we propose a new two-dimensional optical phased array reflector that can realize two-dimensional beam steering. The reflector adopts an easy-to-integrate area array structure and employs the dispersion characteristics of the Gires-Tournois resonant near the resonance wavelength to amplify the phase shift. Simulation results showed that the structure has a high phase shift efficiency near the resonance wavelength, and provides a new solution for realizing two-dimensional beam steering.
