TransWave Photonics, LLC proposes to demonstrate a mid-infrared 2-dimensional beam-steering photonic integrated circuit (PIC) with a passive InGaAs/InP platform where high performance mid infrared quantum cascade laser sources, low-loss InGaAs waveguides, and beam steering photonic elements are monolithically integrated. Low mid-infrared optical loss of the undoped InGaAs waveguide core and undoped InP cladding layers in the passive waveguides will enable low-loss light propagation and integration of multiple elements to achieve all-electrical beam steering operation. Our proposed beam steering microchip is expected to achieve horizontal beam steering larger than +/-10 degrees and vertical beam steering larger than +/- 25 degrees with a diffraction limited beam delivering more than 1-watt continuous-wave output power.
