Nonlinear Terahertz Polaritonics in a Quantum Paraelectric
Chao Shen, Carla Verdi, Serafim Babkin +2
Terahertz (THz) frequency range holds immense potential for high-speed data processing and signal manipulation. However, a fundamental challenge remains: the efficient and tunable…
Interferometric determination of intrinsic nonlinear Kerr index in lead-halide perovskites
Dusan Lorenc, Ayan Zhumekenov, Osman M. Bakr +1
Lead halide perovskites have recently been reported to demonstrate an exceptionally high nonlinear (Kerr) refractive index n of up to 10 cm/W in CHNHPbBr…
Dispersive effects in ultrafast non-linear phenomena
Dusan Lorenc, Zhanybek Alpichshev
It is a basic principle that an effect cannot come before the cause. Dispersive relations that follow from this fundamental fact have proven to be an indispensable tool in physics…
Mid-infrared Kerr index evaluation via cross-phase modulation with a near-infrared probe beam
Dusan Lorenc, Zhanybek Alpichshev
We propose a simple method to measure nonlinear Kerr refractive index in mid-infrared frequency range that avoids using sophisticated infrared detectors. Our approach is based on u…
