mode field diameter conversion optical waveguide fiber, the change in refraction factor method and optical waveguide manufacturing method of the cosmetic material

摘要

this invention is a relationship between the optical fiber and the fiber collimator, optical waveguide coupler, a light filter, the light separator, the periodic diffraction, dispersion compensation, simulation of the raman effect of the cascade switch mode field diameter fiber, physical value sensor, erbium fiber amplifier of gain. the effect of number of words, in order to a predetermined wavelength of radiation to be used in the control unit. according to the invention, the optical waveguide for easy. the method of the chemical coating of the optical waveguide (1) with a plastic material to manufacture the tube (24) for the supply of molecular gas mixture of the silicon atom is a party 3 in the oxygen atom of oxygen per 1000, a son who will fall in uc9c8uc18cuc6d0 mixed. refractometer is the optical waveguide (1), and the local strain.this is a core (3) contains an element (2) to the primary station or the local thermal diffusion can be. optical waveguide (1) and the arc (10), electric current i of the infrared laser (15) and (16) of the filament. the core (3) 0.01 five atomic% as the concentration of nitrogen doping. mode field diameter of the fiber core (3) change in diameter is the length of the waveguide (1) with a change of government, and (4) to increase.
