The 27th OFS conference (OFS 2022) will be held in Alexandria, Virginia, a historic port town on the banks of the Potomac River, approximately 5 miles south of the Nation’s capital, during 29 August - 2 September 2022. Conference Scope & Topics Physical, mechanical, and electromagnetic sensors (including acoustic sensors) Chemical, environmental, biological and medical sensors and biophotonics Interferometric, polarimetric and laser based sensors (including gyroscopes and resonators) Micro- and nano-structured fiber sensors (including photonic crystal fiber and grating based sensors) Distributed and multiplexed sensing and sensor networking Other technologies (including imaging-related, spectroscopic and those based on smart-phone platforms). Environmental, security, defense and industrial applications; technology commercialization and standardization Smart structures (including structural health monitoring and photonics in additive manufacturing) New elements (fibers, devices and subsystems), effects (e.g., plasmonics), technologies (including nanophotonics) and materials (e.g., meta- and structured-materials etc.) for photonic sensing Integrated photonics, cavity opto-mechanics and quantum sensing techniques, precision metrology, frequency combs You can view the published papers here: https://opg.optica.org/conference.cfm?meetingid=57&yr=2020
