The coherent anti-Stokes Raman spectroscopy (CARS) spectrum of the Q-branch of the ν1 band of natural H2S has been measured at a pressure of 1.3 kPa with continuous-wave excitation in the cavity of an argon-ion ring laser. For comparison with the experimental spectrum, Raman line positions and intensities were calculated from energy levels and wave functions that were previously obtained from the study of the pure rotation spectrum and the 2ν2, ν1, and ν3 bands by Fourier transform infrared spectroscopy. These Raman line positions and intensities formed the basis for the simulation of the theoretical CARS spectrum, which is in excellent agreement with the experimental one.

AbstractControlling nonlinear optical signals electrically offers many opportunities for technological developments. Lanthanide-activated nanoparticles have recently emerged as leading platforms for nonlinear upconversion of infra-red excitation within nanometric volumes. However, manipulation of upconversion emission is restricted to varying percentages of component materials, nanocrystal structure, and optical pumping conditions. Here, we report temporal modulation of anti-Stokes luminescence by coupling upconversion nanoparticles with an electrochemically responsive molecule. By electrically tailoring orbital energy levels of the molecules anchored on nanoparticle surfaces, we demonstrate reversible control of molecular absorption, resulting in dynamic colour editing of anti-Stokes luminescence at single-particle resolution. Moreover, we show that a programmable logic gate array based on opto-electrochemical modulation can be constructed to convert information-encrypted electrical signals into visible patterns with millisecond photonic readout. These findings offer insights into precise control of anti-Stokes luminescence, while enabling a host of applications from low-threshold infrared logic switches to multichannel, high-fidelity photonic circuits.
