A 1-D Heterodyne Lens-Free Optical Phased Array Camera With Reference Phase Shifting

This paper presents the first integrated silicon photonics optical phased array (OPA) receiver with imaging capabilities. A 32-element one-dimensional (1-D) OPA with an overall aperture size of 96 &#x00D7; 50 &#x03BC;m<sup>2</sup> is used to generate an electrically steerable &am...
