Abstract

We develop a 2-D non-periodic optical phased array for beam steering in the mid-infrared spectral region in an InGaAs-InP platform. The device consists of an MMI light-splitting tree, thermally isolated thermo-optic phase shifters, and total internal reflection mirror emitters. The device achieves X resolvable points across a steering range of ±14° in both the longitudinal and azimuthal directions.
