Conic optical fibre micro spherical discrete spectrum amplifier

Abstract

The conic fiber micro spherical discrete spectrum amplifier has laser light source, fiber coupler, antireflection coupling lens, conic fiber, micro spherical device and antireflection coupling lens set successively in the light propagation direction. In the incident light end of conic fiber, the first pumping light source is set; and to the micro sphere of the micro spherical device, the second pumping light source is set. The micro sphere of the micro spherical device is embedded between the casing of the micro spherical device and the middle layer or inner core of the conic fiber. The amplifier can convert the input continuous laser into output amplified pulse light.

Description

Technical field: [0001] The invention is related to the optical fiber and is a discrete spectrum amplifier of the cone-shaped optical fiber microsphere. Primarily used in optical amplification systems that vary nonlinearly in a controlled manner. Background technique: [0002] Ming Cai (Ming cai) and others published the paper "Observation of Critical Coupling in the Tapered Optical Fiber and Silica Microsphere Whispering Gallery System" in American Physical Review Letters, Vol. 85, No. 1, July 3, 2000. Coupling in a Fiber Taper to a Silica-Microsphere Whispering-Gallery Mode System) studied the performance of the interaction between the fiber taper and the silica microsphere. But there is no device that develops this characteristic for converting the continuous spectrum into a discrete spectrum and amplifying the discrete spectrum signals. Invention content: [0003] The purpose of this invention is to provide a kind of tapered optical fiber microsphere discrete spectru...
