Device for modulating light source and optical chip comprising same

The invention provides a device for modulating a light source and an optical chip comprising the same, and belongs to the technical field of quantum optics and quantum information. Because the modulator arranged on the micro-ring is coupled with the harmonic generator through the micro-ring, the phase modulator on the micro-ring can modulate the phase of the recovered pump light to control the input pump light to be opened, and the input pump light passes through the harmonic generator to generate the parametric light with half wavelength to be used as a light source. Therefore, the device is favorable for generating an on-chip integrated opening-controlled single photon source, and can meet the integration requirements of current systematic products. 本申请提供一种用于调制光源的装置及包含其的光芯片，属于量子光学及量子信息技术领域。因为本申请将设置在微环上的调制器与谐波产生器通过微环耦接，该微环上的相位调制器可通过调制回收的泵浦光的相位以控开输入的泵浦光，并且将输入的泵浦光通过谐波产生器后生成波长减半的参量光以用作光源。因此该装置有利于生成片上集成的控开单光子源，能够满足当下系统性产品的集成化需求。
