Slow-light fourier transform interferometer.

چکیده
We describe a new type of Fourier transform (FT) interferometer in which the tunable optical delay between the two arms is realized by using a continuously variable slow-light medium instead of a moving arm as in a conventional setup. The spectral resolution of such a FT interferometer exceeds that of a conventional setup of comparable size by a factor equal to the maximum group index of the slow-light medium. The scheme is experimentally demonstrated by using a rubidium atomic vapor cell as the tunable slow-light medium, and the spectral resolution is enhanced by a factor of approximately 100.

Group-delay measurement using the Fourier transform of an interferometric cross correlation generated by white light.
A new method and apparatus for measuring the group delay in optical components and laser cavities are described. Cross-correlational fringes are fully recorded with a Michelson interferometer, in one of whose arms the optics to be measured are inserted. The path difference of the interferometer is calibrated to subwavelength accuracy, and the group delay is calculated from the phase of the Four...
متن کاملInterferograms Analysis for Wavelength Scanning Interferometer Using Convolution and Fourier-transform
A convolution and fast Fourier transform methods are proposed separately to analysis a set of interferograms obtained from measurement results of a wavelength scanning interferometer. This paper describes wavelength scanning interferometer setup and the operation principle. Mathematical explanations, for both interferograms analysis methods, are presented. Results of measuring 3μm step height s...
متن کاملA simple terahertz spectrometer based on a low-reflectivity Fabry-Perot interferometer using Fourier transform spectroscopy.
A simple terahertz (THz) Fourier transform spectrometer is theoretically and experimentally demonstrated with a low-reflectivity Fabry-Perot interferometer. Composed with only two parallel low reflectivity surfaces, this simple spectrometer has the ability to measure the spectrum over more than one octave with a controllable resolution. The emission spectra of a wavelength-tunable photonic tran...
متن کاملFourier Transforms By White-Light Interferometry: Michelson Stellar Interferometer Fringes
The white-light compensated rotational shear interferometer (coherence interferometer) was developed in an effort to study the spatial frequency content of passively illuminated white-light scenes in real-time and to image sources of astronomical interest at high spatial frequencies through atmospheric turbulence. This work was inspired by Professor Goodman’s studies of the image formation prop...
متن کاملObserving Beam Motion Using Infrared Interferometry
Phase noise in the RF master oscillator driving synchrotron oscillations of the beam has been identified as one of the dominant sources of noise in the infrared beamline at the Advanced Light Source. We present measurements of the effect of the electron beam motion in a Fourier transform interferometer (FTIR) detector. This form of detector may be sensitive to very small beam motions.
