Abstract
A nonlocal wavelength-to-time mapping method based on the entangled photon sources is proposed for nonlocal wavelength measurement. In this approach, the spectrally modulated optical carrier from the signal path is detected the single-photon detector. The dispersive medium is applied on the idler path before the idler photons reaches another SPD. With the help of GVD, the frequency correlation is transformed to the correlation of arrival time, when observed in coincidence count. As a result, the spectral pattern of the signal photon can be nonlocally transformed into temporal shape, even though there is no dispersion in the signal path. A proof-of-concept experiment demonstrates the wavelength measurement around 1560 nm, with a resolution of 0.2 nm.
