High-resolution air-clad imaging fibers

Opt Lett. 2018 Nov 1;43(21):5311-5314. doi: 10.1364/OL.43.005311.

Abstract

We present a coherent fiber bundle comprising over 11,000 doped silica cores separated by an air-filled cladding. The fiber is characterized, and its imaging quality is shown to be a substantial improvement over the commercial state of the art, with comparable resolution over an unparalleled spectral range.
