Optical phased arrays (OPAs) with the ability of dynamic beam-steering hold great promise for industrial applications. Although they potentially offer high-resolution, high-speed and wide-angle beam-steering, 2D beam-steering has only been achieved by 1D OPAs with wavelength-tuning or by 2D OPAs containing enormous numbers of elements, thereby sign...

... The requirement for broadband operation of the photonic integrated circuit (PIC) as well as the laser-PIC coupling would also be removed. Singlewavelength, two dimensional beam-steering has been demonstrated using a switched multi-OPA approach [27,28], via the integration of a liquid-crystal filled cavities [29], by active tuning of the emitters [30] and using a single emitter on a thermally activated 2D MEMS cantilever [31]. Currently, none of these solutions offer 2D beam scanning with a satisfactory combination of high frequency operation, wide angular range and low power consumption for demanding sensor applications. ...
