Design of a programmable spiral phase mirror
Fabio Antonio Bovino, Matteo Braccini, Mario Bertolotti
We designed a metallic programmable mirror for optical wavelengths made up of a large number of discrete steps which can be moved independently by actuators. The device is able to…
Orbital Angular Momentum in Noncollinear Second Harmonic Generation by off-axis vortex beams
Fabio Antonio Bovino, Matteo Braccini, Maurizio Giardina +1
We experimentally study the behavior of orbital angular momentum (OAM) of light in a noncollinear second harmonic generation (SHG) process. The experiment is performed by using a t…
Fabrication of GaN/AlGaN 1D photonic crystals designed for nonlinear optical applications
T. Stomeo, G. Epifani, V. Tasco +8
In this paper we present a reliable process to fabricate GaN/AlGaN one dimensional photonic crystal (1D-PhC) microcavities with nonlinear optical properties. We used a heterostruct…
Management of the orbital angular momentum of vortex beams in a quadratic nonlinear interaction
Fabio A. Bovino, Matteo Braccini, Mario Bertolotti +1
Light intensity control of the orbital angular momentum of the fundamental beam in a quadratic nonlinear process is theoretically and numerically presented. In particular we analyz…
GaN/AlGaN microcavities for enhancement of non linear optical effects
V. Tasco, I. Tarantini, A. Campa +8
We present a study on the design, growth and optical characterization of a GaN/AlGaN microcavity for the enhancement of second order non linear effects. The proposed system exploit…
Bound and free waves in non-collinear second harmonic generation
M. C. Larciprete, F. A. Bovino, A. Belardini +2
We analyze the relationship between the bound and the free waves in the noncollinear SHG scheme, along with the vectorial conservation law for the different components arising when…
