Dynamical control of interference using voltage pulses in the quantum regime
, 2014 As a general trend, nanoelectronics experiments are shifting toward frequencies so high that they become comparable to the device's internal characteristic time scales, resulting in new opportunities for studying the dynamical aspects of quantum ...

Recent advances in organic broad‐spectrum photodetection materials and devices
InfoMat, EarlyView.Graphical Abstract This review systematically outlines the evolution of organic photodetectors from fullerene‐based to advanced non‐fullerene acceptors, highlighting how molecular engineering (e.g., D–A, quinoidal, and A‐D‐A′‐D‐A architectures) extends spectral response into the short‐wave infrared region.

AIP Advances, 2018 The modulation capability of a terahertz dynamic metasurface was enhanced by integrating it with an asymmetric Fabry-Pérot cavity. The dynamic metasurface consists of split ring resonators combined with high frequency metal semiconductor metal varactors.

Resonant backward scattering of light by a two-side-open subwavelength metallic slit
, 2005 The backward scattering of TM-polarized light by a two-side-open subwavelength slit in a metal film is analyzed. We show that the reflection coefficient versus wavelength possesses a Fabry-Perot-like dependence that is similar to the anomalous behavior ...

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy
Journal of Raman Spectroscopy, EarlyView.We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

Measuring the speed of light using beating longitudinal modes in an open-cavity HeNe laser
, 2010 We describe an undergraduate laboratory that combines an accurate measurement of the speed of light, a fundamental investigation of a basic laser system, and a nontrivial use of statistical analysis.

Journal of Raman Spectroscopy, EarlyView.Inter‐Theta‐Gram spectroscopy enables super‐spectral‐resolution Raman analysis by jointly reconstructing the excitation laser line and Raman peak during an etalon angle scan, yielding internally referenced Raman shifts. Demonstrated on lab‐grown versus natural diamond, it resolves 0.1–0.2 cm−1 Raman‐shift offsets that are invisible in conventional ...

Electronics Letters, 1982 The use of a spherical mirror Fabry–Perot (confocal) interferometer as an optical displacement sensor is described. The device incorporates a simple electronic servo to maintain the interferometer at an operating point of maximum sensitivity. Applications as vibration and acceleration sensors are forseen, with sensitivities for sinusoidal accelerations
