Spatial modulation characteristics of single-photon fre- quency up-conversion systems pumped by Gaussian la- ser beam
In a Gaussian laser beam pumped single-photon frequency up-conversion system, the spatial distribution of the con- version efficiency is calculated, which strongly depends on the intensity distribution of the pump beam and leads to a spatial modulation of the output single photons. As a result, by s...

description | In a Gaussian laser beam pumped single-photon frequency up-conversion system, the spatial distribution of the con- version efficiency is calculated, which strongly depends on the intensity distribution of the pump beam and leads to a spatial modulation of the output single photons. As a result, by simply varying the Gauss/an pump beam intensity and the beam size, the converted photons could be modulated spatially and exhibit a programmable distribution. This will be meaningful for the researches on quantum communication and quantum manipulation based on frequency up-conversion svstem. |
