Light guide optical fiber andlight guide system thereof co-composing by coaxial semiconductor light source and light detector

Abstract

The invention relates to a coaxial light-guide optical fiber for a coaxial light-guide system, which is manufactured by distributing refractive indexes on the radius and is different from the prior optical fiber which is formed by distributing the refractive indexes on the diameter, wherein the refractive indexes of a circular shell and an axle center part which are coaxial with each other are the same; the center of refractive index distribution which is taken as the light-guide basis is shifted from an axle center to the radius of the optical fiber; and light is changed to be transmitted between the axle center and the circular shell which is coaxial with the axle center. Not only the novel orientation solves the problem that the refractive index distribution center of the prior optical fiber after manufacture is concave but also the luminous flux of the coaxial monomode fiber manufactured by the invention is larger than that of the prior monomode fiber, thereby increasing the communication distance. When the coaxial light-guide optical fiber is matched with an inner conductor and an outer conductor which are invented for coaxial power supply and are partitioned by a coaxial light source and a coaxial light tester which are formed by multilayered annular semiconductors, not only the problem of energy consumption when lateral emitting elliptical light sources are emitted into a circle core is solved but also the coaxial optical fiber, the coaxial light source and the coaxial light tester can be integrated into the perfectly photoelectrically matched coaxial light-guide system.

Description

technical field [0001] The invention relates to a coaxial light guide system co-constructed with an optical fiber used for communication, a light source and a light detector. Background technique [0002] Humans discovered glass 2,500 years ago, and it was not until the Roman era that glass was drawn into filaments for use. In the 1950s, the medical community used these bare-wire glass bundles to transmit images, hoping to make an endoscope; but the light leakage was too large to transmit the image clearly, because these bare-wire glasses had low purity and were made of air with a low external refractive index. Make a fully reflective layer. In 1956, Dr.Narinder Singh Kapany first coined the name "fiber optical" for the purpose of more accurately wrapping a layer of glass material with a lower refractive index on the bare glass filament as a shell, which can controllably cause total reflection and avoid The light leaks out to achieve a more complete optical fiber transmiss...

Problems solved by technology

The unstable current caused by this is not conducive to the increase of power, so that high-power output cannot be done, and it cannot replace the side-firing laser.

Therefore, the elliptical light output of side-fired lasers matching the circular core is still a shortcoming that does not conform to the laws of nature
