This paper presents the case of an optical phased array in analogy with its counterpart in the microwave frequency region. It consists of a planar aperture array formed by the discrete illuminated core ends of a number of monomode optical fibres placed adjacent to each other in several rows.

Optical phased array with on-chip phase calibration
Optics Letters, 2022Optical phased arrays (OPAs) with phase-monitoring and phase-control capabilities are necessary for robust and accurate beamforming applications. This paper demonstrates an on-chip integrated phase calibration system where compact phase interrogator structures and readout photodiodes are implemented within the OPA architecture. This enables phase-error

Applied Optics, 2014
We demonstrate a ladar with 0.5 m class range resolution obtained by integrating a continuous-wave optical phased-array transmitter with a Geiger-mode avalanche photodiode receiver array. In contrast with conventional ladar systems, an array of continuous-wave sources is used to effectively pulse illuminate a target by electro-optically steering far ...

Optical phased array technology
Proceedings of the IEEE, 1996Optical phased arrays represent an enabling new technology that makes possible simple affordable, lightweight, optical sensors offering very precise stabilization, random-access pointing programmable multiple simultaneous beams, a dynamic focus/defocus capability, and moderate to excellent optical power handling capability.

Waveguide-Based Optical Phased Array
IEEE Photonics Technology Letters, 2013A concept for a 3-D waveguide system, which can be used for optical phased arrays, is presented in this letter. We implemented static phased arrays with rod waveguides of different widths, which can be used for holographic applications. They are fabricated with direct laser writing, a technique based on two photon polymerization. As the element size of
