Multimode emission of fluorinated ethylene propylene clad large diameter liquid-core lasers
Anand Dewansingh, Abigail Deaton, Cortland Bergman +3
A liquid-core (LiCo) dye laser was demonstrated using Rhodamine B (RhB) dissolved in glycerol as the gain medium and fluorinated ethylene propylene (FEP) tubing as the waveguide. P…

Neon tetra fish (Paracheirodon innesi) as farm-to-optical-table Bragg reflectors
D. Ryan Sheffield, Anthony Fiorito, Hengzhou Liu +2
Iridophore networks in the skin of neon tetra fish are investigated for use as biologically sourced, tunable, Bragg reflector arrays. This paper reports on a method for immediate a…
