Abstract
The demand for optical technologies in space is growing rapidly driven by the advent of low-earth orbit satellite “mega-constellations” providing global communication services. Free space optical communications between satellites in low earth orbit presents a number of technology challenges related to maintaining stable links between two satellites separated by thousands of kilometers. One principal challenge is the development of mechanically robust, mass-producible beam-steering technologies with low SWaP, and recurring cost. One potential solution to this challenge is to replace costly mechanical steering mechanisms with beam-steering elements such as on-chip optical phase arrays. This work presents ongoing research towards the development of an on-chip wide-steering optical phase array for inter-satellite communications. The presentation will cover the system architecture, component design, and control algorithms for synchronizing many emitters into a single output beam.
