The Laboratory of Fiber Optics (LFO) is part of the Materials Science Institute of the University of Valencia and all the members of the LFO belong to the Faculty of Physics. The LFO has the equipment for the fabrication of photonic crystal fibers (PCFs) and special fiber-optics components based on acousto-optic interaction, photo-inscription of diffraction gratings and fiber tapering.

The research projects of the group involve the fabrication of special fiber components and PCFs, and their exploitation in different fields as new optical fiber light sources and lasers, sensors and microwave photonics. The main achievements of the Laboratory include the fabrication of PCF with special polarization and dispersion properties, erbium, ytterbium and germanium doped PCF and the preparation of PCF tapers. For years, we have been developing new fiber light sources such as Q-switched and mode-locked lasers, white light supercontinuum and photon pairs sources. Recently, we have developed a technique to fabricate tunable microcavities and micro-capillaries with submicrometric wall thickness for highly sensitive chemical sensors.
