1 Sep 2016 | Abstract: | We calculate that an appropriate modification of the field associated with
only one of the photons of a photon-pair can suppress generation of the pair
entirely. From this general result, we develop a method for suppressing the
generation of undesired photon-pairs utilizing photonic stop-bands. For a
third-order nonlinear optical source of frequency-degenerate photons we
calculate the modified frequency spectrum (joint spectral intensity or JSI) and
show a significant increase in a standard metric, the coincidence to accidental
ratio (CAR). These results open a new avenue for photon-pair frequency
correlation engineering. | Source: | arXiv, 1609.0106 | Services: | Forum | Review | PDF | Favorites |
