| 其它 | We introduce a method for achieving high-efficiency and broadband fiber interfaces to silicon photonic devices at cryogenic temperatures, utilizing edge coupling between waveguides and lensed fibers. We will describe the simulation, design, and fabrication of single-sided waveguides featuring Bragg mirrors and tapered mode converter optimized for maximum photon collection from emitters in the devices. We then present fabrication techniques, including deep etching for edge coupling, as well as the experimental setup used to test our devices at cryogenic temperatures. Our method will enable the integration of quantum emitters to silicon photonics, a promising platform for scalable photonic quantum computing and communication. |
