OPTICAL AMPLIFIER HAVING ACTIVE CONTROLLED WAVE PROFIT AND OPTICAL FIBER SOURCE HAVING CHANGABLE OUTPUT SPECTRUM

摘要

PURPOSE: An optical amplifier and optical fiber source is provided to gain a profit rate in each wavelength and to gain a changeable output spectrum in various shapes. CONSTITUTION: In the optical amplifier, overall profit rate function has a desired shape by including a profit medium presenting an optical profit, pump for pumping the optical profit, an optical incidence tool in which an optical signal is incident to the profit medium, at least more than one wavelength changeable filter having loss rate function. In the optical fiber source, a spectrum of an amplified and voluntary emitting light generated from a profit optical fiber has a desired shape in output section by including a profit optical fiber in a predetermined length, an optical pump forming voluntary emitting light, at least more than one wavelength changeable filter having a loss function, a filter driver for applying an electric signal controlling a loss function.
