Dispersion-engineered Optical Phased Array for Aliasing-free Beam-steering with a Plateau Envelope

Not Accessible

Your library or personal account may give you access

Abstract

We design and fabricate a chip-scale optical phased array (OPA) with a uniform emitting structure composed of bent waveguides. This silicon-on-insulator based device demonstrates aliasing-free beam-steering over the entire field-of-view available (-34°~34°), with a far-field addressability of 6.71°. In addition, the steering process exhibits a plateau envelope, with an intensity fluctuation of less than 0.45 dB from -30°~30°.
