Inventor: HWANG SEONG TAEK
IPC: H01S3/06
Filed: 1999-07-21
Abstract: PURPOSE: A broad band light source using a seed-beam is provided to reduce the intensity difference of an output light by raising the intensity of the output light, thereby reducing the error of measurement. CONSTITUTION: A broad band light source(200) consists of a seed-beam light source(202), a first optical isolator(208), a first optical coupler(210), a first pumping light source(212), an optical fiber with the rare-earth (214), a second optical coupler(216), a second pumping light source(218), and a second optical isolator(220). The seed-beam light source outputs a seed-beam of preset wavelength band. The first optical isolator isolates a reverse ASE(amplified spontaneous emission) output from the front end of the optical fiber with the rare-earth to the seed-beam light source, thereby preventing the distortion of the seed-beam. The first optical coupler couples the seed-beam of the seed-beam light source with an input pumping light to output the coupled light to the front end of the optical fiber. The second optical coupler outputs an input pumping light of the second pumping light source to the rear end of the optical fiber. The second optical isolator prevents the ASE from being emitted to the rear end of the optical fiber, thereby preventing the deterioration of the amplify efficiency.
