Abstract

Fiber-tip sensors have been used extensively for measuring chemical and physical parameters. Particularly, multimode fibers (MMF) tip sensors have become attractive since they open the possibility of using simple light-emitting diodes. While common techniques to fabricate MM fiber-tip sensors are labor-intensive, we developed a simple and controllable method to transfer large-area nanophotonic structures to the fiber end-face by mechanical contact, without using glue or micromanipulator. As proof of concept, a 2D photonic crystal (PhC) was successfully transferred to the tip of a multimode fiber, and its response to changes in refractive index was characterized, obtaining a sensitivity of 244 nm/RIU.
