Platforms for integrated nonlinear optics compatible with silicon integrated circuits
David J. Moss, Roberto Morandotti
Nonlinear photonic chips are capable of generating and processing signals all-optically with performance far superior to that possible electronically - particularly with respect to…
Terahertz bandwidth integrated radio frequency spectrum analyzer via nonlinear optics
Marcello Ferrera, Christian Reimer, Alessia Pasquazi +7
We report an integrated all-optical radio frequency spectrum analyzer based on a ~ 4cm long doped silica glass waveguide, with a bandwidth greater than 2.5 THz. We use this device…
New CMOS Compatible Platforms for Integrated Nonlinear Optical Signal Processing
D. J. Moss, R. Morandotti
Nonlinear photonic chips have succeeded in generating and processing signals all-optically with performance far superior to that possible electronically - particularly with respect…
Temporal and Spectral Shaping of Broadband THz Pulses in a Photoexcited Semiconductor
Mostafa Shalaby, Marco Peccianti, David G. Cooke +2
Transmission through photoexcited semiconductors is used to temporally and spectrally shape a Terahertz pulse. By adjusting the optical pump-THz probe delay, we experimentally intr…
Terahertz Magnetic Modulator based on Magnetically-Clustered Nanoparticles
Mostafa Shalaby, Marco Peccianti, Yavuz Ozturk +3
Random orientation of liquid-suspended magnetic nanoparticles (Ferrofluid) gives rise to zero net magnetic orientation. An external magnetic field tends to align them into clusters…
Novel architecture for ultra-stable micro-ring resonator based optical frequency combs
Alessia Pasquazi, Lucia Caspani, Marco Peccianti +8
We report a novel geometry for OPOs based on nonlinear microcavity resonators. This approach relies on a self-locked scheme that enables OPO emission without the need for thermal l…
