MY PERSONAL RESEARCH TOPICS

- DESIGN AND CHARACTERIZATION OF INTEGRATED-OPTIC DEVICES FOR OPTICAL COMMUNICATIONS

Integrated optics devices based on with high performance have been designed (and characterized), by using an innovative technique that allows tailoring separately the amplitude and phase of a 1D photonic-crystal's transfer function. This technique allows obtaining filters with an almost-ideal transfer function, and hence they can be successfully exploited to filter optical signals with very high bit-rate.

 

- FIBER OPTIC NONLINEAR EFFECTS: ANALYSIS AND STUDY OF POSSIBLE COMPENSATION TECHNIQUES

In this research field a method for the compensation of nonlinear optical distortions has been identified and demonstrated, both theoretically and experimentally. This result, obtained by an appropriate use of nonlinear devices for optical phase conjugation, opened the way to the possibility of implementing real optical-transmission systems realizing simultaneous dispersion and nonlinearity compensation.

 

- STUDY AND CHARACTERIZATION OF INNOVATIVE NONLINEAR OPTICAL MATERIALS:

The use of lithium niobate (LN) crystals for nonlinear optics applications is strongly limited by the photorefractive effect, which causes a distortion of the refractive indices of the material, and can also produce a complete distortion of the propagating optical beam, thus making the crystal unusable. The performed research has demonstrated that a relevant reduction of LN photorefractivity can be obtained by doping the crystal with a small quantity of tetravalent ions, without producing a significant change of crystal quality.

 

- DESIGN AND REALIZATION OF MICRO-STRUCTURED OPTICAL DEVICES FOR BIOPHOTONIC APPLICATIONS

The most significant result obtained in this activity has been the first demonstration of the possibility to use optical beam output from a fiber to trap and move microscopic particles (thanks to the radiation pressure) without any physical contact.
