Raman Shifting induced by Cascaded Quadratic Nonlinearities for Terahertz Generation
Koustuban Ravi, Franz X. Kärtner
We introduce a new regime of cascaded quadratic nonlinearities which result in a continuous red shift of the optical pump, analogous to a Raman shifting process rather than self-ph…
Terahertz-induced cascaded interactions between spectra offset by large frequencies
Koustuban Ravi, Franz X. Kärtner
We explore the dynamics of a system where input spectra in the optical domain with very disparate center frequencies are strongly coupled via highly phase-matched, cascaded second-…
Effective Path Towards Relativistic Transients at Millimeter Wavelengths
Sergio Carbajo, Anne-Laure Calendron, Huseyin Cankaya +6
We refine the method towards extraction of sub-cycle transients in the 0.1-1 THz frequency (mm-wavelength) range from optical rectification in lithium niobate using tilted pulse fr…
A multi-band, multi-level, multi-electron model for efficient FDTD simulations of electromagnetic interactions with semiconductor quantum wells
Koustuban Ravi, Qian Wang, Seng-Tiong Ho
We report a new computational model for simulations of electromagnetic interactions with semiconductor quantum well(s) (SQW) in complex electromagnetic geometries using the finite…
