Power-recycled Michelson interferometer with a 50/50 grating beam splitter
We designed and fabricated an all-reflective 50/50 beam splitter based on a dielectric grating. This beam splitter was used to set up a power-recycled Michelson interferometer with a finesse of about FPR ≈ 880. Aspects of the diffractive beam splitter as well as of the interferometer design are discussed.
متن کاملDispersive white-light spectral interferometry with absolute phase retrieval to measure thin film.
We present a white-light spectral interferometric technique for measuring the absolute spectral optical path difference (OPD) between the beams in a slightly dispersive Michelson interferometer with a thin-film structure as a mirror. We record two spectral interferograms to obtain the spectral interference signal and retrieve from it the spectral phase, which includes the effect of a cube beam ...
متن کاملPolarization-mode-dispersion compensator using a polarization beam splitter and quarter-wave plates.
We propose a Michelson-interferometer-type polarization-mode-dispersion (PMD) compensator with one polarization beam splitter and quarter-wave plates. We experimentally demonstrate the proposed PMD compensator with fiber devices and show the PMD compensation ability to be 104 ps by the fixed-analyzer method.
متن کاملThe geometric phase : interferometric observations with white light P . HARIHARAN
Observations on white-light interference fringes show that the effects due to the introduction of a variable geometric phase, which is independent of the wavelength, differ significantly from those due to a change in the optical path difference . 1 . Introduction Berry [1] has shown that the wavefunction of a quantum system may acquire an additional phase factor (the geometric phase) when the s...
متن کاملPolarizing beam-splitter based on defective photonic crystals
The performance of a polarizing beam splitter based on the one-dimensional photonic crystals (1D-PCs), is theoretically investigated. The polarizing beam splitter consists of a symmetric stack of the low-index quarter-wave plates and the high-index half-wave plates with a central defect layer of air. The linear transmission properties of the polarizing beam splitter are numerically simulat...
