Frequency Correlated Bi-Photon Spectroscopy using a Tunable Up-Conversion Detector
Oliver T. Slattery, Lijun Ma, Paulina S. Kuo, Yong-Su Kim, Xiao Tang
We demonstrated a scheme for frequency correlated bi-photon spectroscopy using a strongly non- degenerate down-conversion source and a tunable up-conversion detector. In this scheme, the spectral function at one wavelength range of a remote object can be reproduced by locally measuring another wavelength range using an up-conversion detector and monitoring the coincidence counts. The spectral resolution of the system is better than 0.1 nm corresponding to the acceptance width of the detector while the measurement range is determined by the linewidth of then source.
