Publication number: 20250028121Abstract: In an example, the present invention provides a method of manufacturing a polarization-degenerate fiber Bragg grating nanofiber cavity for quantum computing or quantum repeater. The method includes transmitting electromagnetic radiation characterized by a wavelength of 150 nm to 400 nm and longer through a pattern of a phase shift mask to diffract the electromagnetic radiation to form an interference pattern. The pattern is to be illuminated onto a core of a first end of a fiber optical cable region. In an example, the method forms a fiber Bragg grating onto the core of fiber optical cable region by changing a refractive index of the core of fiber optical cable region using the electromagnetic radiation while rotating the fiber optical cable about an axis defined along a length of the fiber optical cable region.Type: ApplicationFiled: July 17, 2023Publication date: January 23, 2025Inventors: Shinya KATO, Akihisa GOBAN, Ryotaro INOUE, Takao AOKI
