Origin, strength, and speed of the nonlinear optical response of transparent conducting oxides to single-cycle optical pulses

Ieng-Wai Un, Subhajit Sarkar, Yonatan Sivan

We present a first-principles study of the nonlinear optical response of transparent conducting oxides at the nanoscale due to excitation by intense, extremely short pulses based o…

Quantum-optical theory of the few femtosecond nonlinear optical response of Drude metals with a non-parabolic conduction band

Ieng-Wai Un, Subhajit Sarkar, Yonatan Sivan

We develop an energy-space density matrix framework to investigate the interaction of extremely short optical pulses (ESPs) with transparent conducting oxides (TCOs). This approach…
