On The Biphoton Wavelength [PDF]
Brazilian Journal of Physics, 2000 We report on an experiment showing that the wavelength of a biphoton is clearly dependent on the measurement scheme and on the way it is defined. It is shown that it can take any value, depending on the control of the interferometer phase differences. It

Performance analysis of Strain sensor based on Fiber Bragg Grating [PDF]
ITM Web of Conferences, 2020 A fiber Bragg grating can be worked as reflector, it is constructed in a short section of optical fiber that reflects light of specific wavelength and allow to pass remaining wavelengths. This is possible by creating a periodic change in refractive index

Wavelength dependence and wavelength selectivity in photochemical reactions [PDF]
Photochemical & Photobiological Sciences, 2019 The concepts of wavelength dependence and wavelength selectivity have been commonly used by organic photochemists for a long time. The aim of the present article is to offer a selection of relevant cases where the choice of the irradiation wavelength played a key role in the outcome of a photochemical path.
