摘要：
A challenge to the past, an optical phased array for far field beam steering with varied High-Contrast Grating (HCG) waveguides is proposed. For one-dimensional beam steering, the laser light is split into N co-directional HCG waveguides. Simulations and calculations shows slow light waveguide output tunable phase with varied HCG dimensions or index. The far field beam steering effect is presented and will be seen clearly by add array element gradually.
