Embry-Riddle Aeronautical University, Inc. received a $199,999 Project Grant from the National Science Foundation (NSF) Directorate for Engineering (CFDA 47.041) awarded October 1, 2026, with completion targeted for September 30, 2028. The research develops optical characterization capabilities for crystalline aluminum gallium arsenide (AlGaAs) mirror coatings by constructing a high-finesse optical cavity with a translation-mounted test mirror. The project will map birefringence—differences in how orthogonal polarizations of light are reflected—across the mirror surface at high resolution to identify sources of non-uniformity that currently limit instrument sensitivity. The primary deliverable is a detailed birefringence mapping dataset and analysis methodology applicable to improving AlGaAs mirror manufacturing processes and estimating birefringence-induced noise in next-generation instruments. This research directly supports advancement of ultra-low-noise optical systems, particularly for interferometric gravitational-wave detectors such as LIGO (Laser Interferometer Gravitational-Wave Observatory) upgrades. The work addresses a critical technical gap, as AlGaAs mirrors currently serve as components in precision timing experiments due to their 10-fold lower thermal noise than amorphous oxide alternatives, yet their optical inhomogeneities remain poorly characterized and represent a potential limiting factor for future detector sensitivity.Federal Project Grant Award Summary
