The optical fiber comprises a light source, a quartz single-mode optical fiber, a quartz optical fiber tapering transition area, a quartz optical fiber tapering stretching part and an ice micro-nano optical fiber, wherein the light source is connected with one end of the quartz single-mode optical fiber, the other end of the quartz single-mode optical fiber is connected with a stretching part of a quartz optical fiber tapering through the quartz optical fiber tapering transition area, and the stretching part of the quartz optical fiber tapering is tightly attached to an input end of the ice micro-nano optical fiber in a coupling manner; and the ice micro-nano optical fiber is formed at a tail end of an ice micro-nano optical fiber support by growing water vapor into ice. The ice micro-nano optical fiber disclosed by the invention can efficiently transmit light waves in a visible light wave band with waveguide loss less than 0.03 dB / cm.

Description

technical field [0001] The invention relates to a micro-nano optical fiber for low-loss transmission of visible light used in the field of photon integration and devices, in particular to an ice-micro-nano optical fiber that can be used for wide-spectrum low-loss optical waveguide. Background technique [0002] Ice is one of the most abundant and important solid substances on the earth, and has extensive research and application value in the fields of physical chemistry, life science, geology, astronomy, and environmental climate. Because ice and water have extremely low optical absorptivity in the ultraviolet to near-infrared region, they are often used as a good optical medium in the fields of optical microscopy and ultraviolet lithography. In addition, optical means such as Raman spectroscopy, near-infrared absorption spectroscopy, and sum-frequency vibration spectroscopy have the advantages of high detection sensitivity, low background noise, and no need to invade the ph...
