Amorphous Silicon Photonic Optical Phased Array for Beam Steering

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


Reduction of mobile mechanical parts in Optical Phased Arrays and the overall miniaturization of the system can be claimed to improve robustness to harsh environment condition and reduction of the overall power consumption. An optical phased array configuration built on structure developed in a silicon photonic integrated circuit technology, may be able provide a solution to fit these requirements. Nevertheless, there is some drawback and some fabrication complexity that can be limiting the direct application for automotive solution in a low-cost configuration. In this work, it is presented the design and the simulation of an amorphous silicon phased array working at a wavelength of 1550 nm. Potential and limitation of this approach will be outlined.
