Schematics of the polymer waveguide-based OPA beam scanner with an integrated laser. (a) 2D beam scanner device consisting of the Bragg reflector, 1 × 32 power splitter, phase modulator array, and beam concentrator fabricated on a single chip. SLD chip, cylindrical lens, and diffraction grating are aligned and attached around the chip. (b) Horizontal beam scanning produced by controlling the phase distribution of the waveguide array through the polymeric phase modulator array. (c) Vertical beam scanning obtained by wavelength tuning of the integrated tunable laser and external diffraction grating.
