Photon energy lifter
Zeno Gaburro, Mher Ghulinyan, Francesco Riboli +3
We propose a time-dependent photonic structure, in which the carrier frequency of an optical pulse is shifted without changing its shape. The efficiency of the device takes advanta…
Photon recycling in Fabry-Perot micro-cavities based on SiN waveguides
F. Riboli, A. Recati, N. Daldosso +5
We present a numerical analysis and preliminary experimental results on one-dimensional Fabry-Perot micro-cavities in SiN waveguides. The Fabry-Perot micro-cavities are for…
Role of microstructure in porous silicon gas sensors for NO
Zeno Gaburro, Paolo Bettotti, Massimo Saiani +4
Electrical conductivity of porous silicon fabricated form heavily doped p-type silicon is very sensitive to NO, even at concentrations below 100 ppb. However, sensitivity stron…
Opposite effects of NO on electrical injection in porous silicon gas sensors
Zeno Gaburro, Claudio J. Oton, Lorenzo Pavesi +1
The electrical conductance of porous silicon fabricated with heavily doped p-type silicon is very sensitive to NO. A concentration of 10 ppb can be detected by monitoring the c…
