Embodiment Construction

[0020] Below with the single photon source that wavelength is 585nm as embodiment in conjunction with accompanying drawing, the specific implementation mode of the present invention is described in detail:

[0021] 1. Design of microcavity film system 201

[0022] According to the fluorescence peak position λ of quantum dots 0 =585nm, the optical microcavity film system whose bandpass peak position is completely consistent with the fluorescence peak position is designed by conventional film system design method, and the microcavity film system is:

[0023] (LH) 11 4L(HL) 11 ,

[0024] where H is high refractive index Nb 2 o 5 film layer, L is low refractive index SiO 2 film layer. The transmission spectrum of the designed optical microcavity is shown as the solid line in Figure 2, and the dotted line in Figure 2 is the emission spectrum of the laser diode. When selecting the laser diode, its emission peak position λ 激 The high transmission area lo...

Abstract

This invention discloses one laser source and quanta point integrated portable micro single photon source, wherein, the laser source is of laser diode and the lighting source is of the three-dimensional optical micro chamber with point imbedded. The invention uses diode chip as underlay orderly distributed with the micro chamber and filter slices. The micro chamber comprises the micro chamber film and triangle grid circle distributed air column.

Description

technical field [0001] The invention relates to quantum information and a single photon source, in particular to a smart, portable miniature single photon light source integrated with an excitation light source and a quantum dot light source. Background technique [0002] Quantum properties have unique functions in the field of information, and may break through the limits of existing classical information systems in terms of increasing computing speed, ensuring information security, increasing information capacity, and improving detection accuracy, so a new branch of discipline was born - Quantum information science. It is the product of the combination of quantum mechanics and information science, including: quantum cryptography, quantum communication, quantum computing and quantum measurement. world's high attention. People are increasingly convinced that quantum information science has created new principles and methods for the development of information science, and w...
