Photonic adaptive optics for wavefront error reconstruction

FY 2020-21 · 2021-03-25

Summary
Current technology relies on radio-frequency communication to and from satellites to ground stations. Optical satellite communications can support much larger bandwidths but require adaptive optical correction systems to correct for atmospheric turbulence and maintain high throughput, but conventional bulk-optics systems can be prohibitively expensive. To mitigate cost and space issues, the Project will develop an on-chip adaptive optics (AO) phase shifting system using the integrated silicon photonic analogue of a deformable mirror. The on-chip “deformable mirror” operates through an array of grating couplers, phase sensors, and phase shifters to correct the wavefront of a free-space optical beam directly in the plane of an integrated photonic chip, leading to numerous advantages, including reduced bulk, reduced cost, and increase volume production.

Description
Current technology relies on radio-frequency communication to and from satellites to ground stations. Optical satellite communications can support much larger bandwidths but require adaptive optical correction systems to correct for atmospheric turbulence and maintain high throughput, but conventional bulk-optics systems can be prohibitively expensive. To mitigate cost and space issues, the Project will develop an on-chip adaptive optics (AO) phase shifting system using the integrated silicon photonic analogue of a deformable mirror.

Description (French)
La technologie actuelle repose sur la communication par radiofréquence entre les satellites et les stations terrestres. Les communications optiques par satellite peuvent prendre en charge des largeurs de bande beaucoup plus importantes, mais nécessitent des systèmes de correction optique adaptative pour corriger les turbulences atmosphériques et maintenir un débit élevé. Toutefois, les systèmes classiques d’optique de masse peuvent être d’un coût prohibitif. Pour atténuer les problèmes de coût et d’espace, le projet développera un système de déphasage d’optique adaptative (OA) sur puce qui utilise l’analogue photonique intégré en silicium d’un miroir déformable. Le « miroir déformable » sur puce fonctionne par l’intermédiaire d’un réseau de coupleurs à réseau, de capteurs de phase et de déphaseurs pour corriger les aberrations du front d’onde d’un faisceau optique en espace libre directement dans le plan d’une puce photonique intégrée. Et cela présente de nombreux avantages, notamment la réduction de l’encombrement, la réduction des coûts et l’augmentation de la production en volume.
Expected Results
In the short term, anticipated outcomes will be strengthened collaborations across industry, academia, and government to support research excellence. In the medium term, anticipated outcomes will be the development of new and potentially disruptive technologies with collaborators. In the long term, find collaborative solutions to public policy challenges and create stronger innovation systems.
Expected Results (French)
À court terme, les résultats prévus seront des collaborations renforcées entre l'industrie, le milieu universitaire et le gouvernement pour soutenir l'excellence en recherche. À moyen terme, les résultats attendus seront le développement de nouvelles technologies potentiellement perturbatrices avec des collaborateurs. À long terme, trouver des solutions collaboratives aux défis des politiques publiques et créer des systèmes d'innovation plus solides.
