Abstract

The invention discloses an ice micro-nano optical fiber which can be used for wide-spectrum and low-loss optical waveguide. Including light source, quartz single-mode fiber, quartz fiber taper transition area, stretched part of quartz fiber taper, ice micro-nano fiber; the light source is connected with one end of the quartz single-mode fiber, and the other end of the quartz single-mode fiber is tapered by the quartz fiber The transition area is connected with the stretched part of the silica fiber taper, and the stretched part of the silica fiber taper is closely coupled and arranged at the input end of the ice micro-nano fiber; the ice micro-nano fiber is at the end of the ice micro-nano fiber support Formed from the growth of water vapor into ice. The ice micro-nano fiber of the invention can efficiently transmit the visible light wave band with a waveguide loss of less than 0.03dB / cm.

Description

technical field [0001] The invention relates to a low-loss micro-nano optical fiber for transmitting visible light used in the field of photonic integration and devices, in particular to an ice micro-nano optical fiber that can be used for broad-spectrum low-loss optical waveguide. Background technique [0002] Ice is one of the most abundant and important solid substances on earth. It has extensive research and application value in the fields of physical chemistry, life science, geology and astronomy, environmental climate and so on. 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, the use of optical methods such as Raman spectroscopy, near-infrared absorption spectroscopy, and frequency vibrational spectroscopy to detect the physical and chemical properties of ice itself has the advantages of hig...
