Abstract: Aspects of the disclosure provide phase shifters as well as systems and methods in which those phase shifters may be utilized. For instance, a system may include a first communications terminal. The first optical communications terminal may include an optical phased array (OPA) architecture including a plurality of phase shifters configured to receive an optical communications beam from a second communications terminal. The plurality of phase shifters includes a first phase shifter consisting of silicon having a slab-contacted NPN junction scheme geometry. The first phase shifter may have a PN junction distance from waveguide center within a range 100 nm to 2 μm, inclusive, and a waveguide core width dimension within a range 500 nm to 2 μm, inclusive. The system may also include the second optical communications terminal.
