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…
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…
Ultra-pure RF tone from a micro-ring resonator based optical frequency comb source
Alessia Pasquazi, Marco Peccianti, Brent E. Little +3
We demonstrate a novel mode locked ultrafast laser, based on an integrated high-Q micr-oring resonator. Our scheme exhibits stable operation of two slightly shifted spectral optica…
Novel extraction algorithm for amplitude and phase measurement of ultrashort optical pulses via spectral phase interferometry
Alessia Pasquazi, Marco Peccianti, Jose Azana +2
We present a novel extraction algorithm for spectral phase interferometry for direct field reconstruction (SPIDER) for the so-called X-SPIDER configuration. Our approach largely ex…
