Description: The subject of the invention is a non-linear optical material for light processing and amplification, which is an organic guest-host hybrid system that contains a transparent polymer and a photoisomerizable dye (oxazolone derivative). This material is in the form of a thin film and is a potentially valuable active medium component in all-optical and electro-optical switches and optical amplifiers for optoelectronics and photonics.
The invention relates to a non-linear optical material for light processing and amplification, which is an organic guest-host hybrid system comprising a transparent polymer (PMMA) and a photoisomerizable dye based on the 5-(4H)-oxazolone and a stilbene derivative. This material reveals effective refractive index manipulation and multimode lasing action, respectively. It is a thin film with a thickness of 14.0 - 17.0 micrometers, where the photoisomerizing dye has a concentration of 0.5 - 5.0% in relation to the weight of the polymer. It is a potentially valuable active medium component in all-optical and electro-optical switches and optical amplifiers for optoelectronics and photonics since: (a) light modulation is repeatable and stable, also in the hundreds of Hz regime, (b) amplified optical signal can be easily generated by an external optical pumping source, (c) signal control, as well as read-in and read-out of the information in real time, is fully available, (d) generation of third-order, nonlinear, optical phenomenon is also observed using a third harmonic generation technique, (e) optical or non-linear optical response is observed only by changing the energy and time regime of the supplied optical signal.
