Optomechanical spectroscopy with broadband interferometric and quantum cascade laser sources.
The spectral tunability of semiconductor-metal multilayer structures can provide a channel for the conversion of light into useful mechanical actuation. Responses of suspended silicon, silicon nitride, chromium, gold, and aluminum microstructures are shown to be utilized as a detector for visible and IR spectroscopy. Both dispersive and interferometric approaches are investigated to delineate t...
متن کاملInterferometric near-infrared spectroscopy (iNIRS): performance tradeoffs and optimization
Interferometric near-infrared spectroscopy (iNIRS) is a time-of-flight(TOF-) resolved sensing modality for determining optical and dynamical properties of a turbid medium. iNIRS achieves this by measuring the interference spectrum of light traversing the medium with a rapidly tunable, or frequency-swept, light source. Thus, iNIRS system performance critically depends on the source and detection...
متن کاملInterferometric time delay correction for Fourier transform spectroscopy in the extreme ultraviolet
We demonstrate a Fourier transform spectrometer in the extreme ultraviolet (XUV) spectrum using a high-harmonic source, with wavelengths as short as 32 nm. The femtosecond infrared laser source is divided into two separate foci in the same gas jet to create two synchronized XUV sources. An interferometric method to determine the relative delay between the two sources is shown to improve the acc...
متن کاملSingle Pulse Phase-Control Interferometric Coherent anti-Stokes Raman Scattering Spectroscopy (CARS)
In coherent anti-Stokes Raman scattering spectroscopy (CARS) experiments, usually the amplitude of the signal is measured and the phase information is lost. With a polarizationand phase-controlled pulse shaping technique, the relative phase between the resonant and non-resonant CARS signals is controlled, and spectral interferometry is performed without an interferometer. Both the real and imag...
متن کاملInterferometric spectroscopy of scattered light can quantify the statistics of subdiffractional refractive-index fluctuations.
Despite major importance in physics, biology, and other sciences, the optical sensing of nanoscale structures in the far zone remains an open problem due to the fundamental diffraction limit of resolution. We establish that the expected value of spectral variance (Σ[over ˜](2)) of a far-field, diffraction-limited microscope image can quantify the refractive-index fluctuations of a label-free, w...
