DOI: 10.1080/10910344.2025.2456241

Abstract: Abstract Hybrid optical surfaces are gaining attention for system miniaturization and enhanced optical throughput, but challenges arise in creating precise tool paths for dual profiles with consistent micro-grooves and minimal form errors. In this study,… read more here.

DOI: 10.1364/ol.449210

Abstract: Laws of reflection and refraction between homogeneous media and gradient index (GRIN) ray behavior are both derived from Fermat's principle. Design methods for GRIN can be difficult to analytically develop. This Letter proposes a foundation… read more here.

DOI: 10.3390/polym15030652

Abstract: Copolymer thin films of glycidyl methacrylate (GMA), ethylene glycol dimethacrylate (EGDMA) and 2,4,6,8-tetramethyl-2,4,6,8-tetravinylcyclotetrasiloxane (V4D4) were synthesized via initiated chemical vapor deposition (iCVD) as protective coatings for optical surfaces. Chemical durability in various solvents, corrosion resistance,… read more here.
