Journal ArticleDOI
The effect of interfacial roughness on the normal incidence bandgap of one-dimensional photonic crystals.
TL;DR: Additional finite-difference time-domain (FDTD) simulations that reveal the effect of interfacial roughness on the normal-incidence reflectivity at several other wavelengths within the photonic bandgaps of various 1DPC quarter-wave stacks and predict that both a narrowing and red-shifting of the bandGaps will occur due to the roughness features.
Journal ArticleDOI
Spectral interferometric coherent Raman imaging.
TL;DR: A low-background and sensitive coherent Raman imaging technique that uses selective excitation of Raman levels with chirped pulses from a single femtosecond laser to obtain the real and imaginary parts of chi(3) simultaneously is proposed.
Journal ArticleDOI

TL;DR: In this article, a single crystal Mott-Hubbard insulator with a ferrimagnetic and orbitally ordered ground state was investigated using ultrafast optical pump-probe reflectivity and magneto-optical Kerr spectroscopy.
Proceedings ArticleDOI
Dynamical electric and magnetic metamaterial response at terahertz frequencies
TL;DR: In this article, the electromagnetic response of planar split ring resonators fabricated on GaAs was characterized using terahertz time domain spectroscopy, and it was shown that optical excitation is sufficient to turn off the electric resonance.
Effects of Substrate Parameters on the Resonance Frequency of Double-sided SRR Structures under Two Different Excitations
TL;DR: In this paper, the authors investigated the efiects of substrate parameters (i.e., the thickness and the permittivity) on the resonance frequency of the double-sided SRR (DSRR) structure under two different excitation conditions.
