Fabrication of Lensed Optical Fibers for Biosensing Probes Using CO<sub>2</sub> and Femtosecond Lasers
We propose a new method for precisely fabricating a lensed fiber with a desired focal length by first cleaving a coreless silica fiber using an ultrafast femtosecond laser without thermal effects and subsequently shaping the radius of curvature at the optical-fiber end using a CO<sub>2</sub...
