摘要
The present invention discloses a method for controlling spectral properties of optical quantum states using quantum interference in cascaded waveguide structure comprises the following steps: adopting a multi-stage cascaded waveguide structure sequentially consisting of a segment of nonlinear medium, a segment of dispersive medium, . . . and a segment of nonlinear medium, or adopting a two-stage cascaded waveguide structure sequentially consisting of a segment of nonlinear medium, a segment of dispersion-controllable dispersive medium and a segment of nonlinear medium; pumping the multi-stage cascaded waveguide structure or two-stage cascaded waveguide structure by using pulsed laser to generate optical quantum states through the cascaded parametric process in the cascaded waveguide structure. The spectral property of the optical quantum state can be flexibly adjusted by changing the number of stages, the length and dispersion property of the dispersive media.
