Fiber and Integrated Optics Laboratory

Welcome to FIOlab

The FIO Lab is engaged in the development of novel photonic devices based on optical fibers and integrated optics. Applications are mainly related to sensing (curvature, temperature, refractive index, salinity, and pressure, for instance) and telecomm (tunable lasers, photonic switches, modulators). Fiber devices are developed using mainly specialty fibers and integrated devices are fabricated using different platforms such as Silicon on Insulator (SOI), polymers, and InP. The FIO Lab is located at the Unidad Aguascalientes, Centro de Investigaciones en Optica, A.C.

Dr. Daniel A. May-Arrioja is currently a full time Researcher at CIO Unidad Aguascalientes.
