History

Integrated optics deals mainly with the management of light ( photons) within micrometric regions, with the aim to control this kind of optical signals either by means of active or passive optical circuits based on channel waveguides. In these devices, the light plays the same role that the electrons and holes do in microelectronics. By using ultrashort intense pulse laser writing, in the last years it has been possible to fabricate optical circuitry including passive ( splitters, couplers, Mach Zehnder interferometers) and active devices (lasers, amplifiers) in fast way and at low cost. In this sense, the CIOp has addressed its research goals to the optical characterization of new integrated devices obtained by means of laser writing in different substrates commonly used as light coherent emitter (lasers) or signal regenerator ( optical amplifiers) for optical communications. For instance, we can show Nd:YAG, Nd:LiNbO3 or Er-Yb:Glass etc.
