Abstract

We demonstrate two-dimensional (2-D) beam-steering using only wavelength control from one-dimensional siliconbased OPA, where path differences are sequentially formed in each channel. With 79.6-μm path difference in phasefeeding lines and a 2-μm pitch in grating radiators, we achieved a continuous transversal steering about 46° and a longitudinal steering near 13° with a wavelength tuning of 90 nm. The single-beam with divergence angle of 4° was formed by phase initialization using electro-optic optic p-i-n phase shifters before beam-steering.
