Research Institution
Spontaneous Parametric Down Conversion (SPDC) is currently an active research area in quantum communications (QC) to develop entangled single photon sources. However, the bandwidth of current SPDC sources is too broad for many applications. NIST researchers have modeled a solution to this problem that reduces the bandwidth by >50. We propose to fabricate a prototype of the NIST device by developing an innovative fabrication method for a Bragg grating with a pi/2 phase shift over the SPDC periodically poled waveguide in lithium niobate. The project goal is to demonstrate significant narrowing of the SPDC spectrum. We anticipate that the result of this Phase II project will be a design for a highly integrated SPDC source that will enable new fundment QC research.
