Publication number: 20020003655Abstract: Disclosed relates to an L-band optical fiber amplifier which amplifies an L-band optical signal of 1570 nm to 1610 nm. In general, when a pumping light of 980 nm for example, output from a pumping light generating laser diode, is supplied to an erbium doped fiber EDF, an amplified spontaneous emission ASE having a bandwidth of 1530 nm to 1560 nm, namely, C-band is generated. The L-band optical fiber amplifier of the invention is configured in a manner that ASE transmitted in the backward direction, or a predetermined wavelength light selected from the bandwidth of 1530 nm to 1560 nm is reflected by a reflecting means and re-injected to EDF. A fiber bragg grating FBG or a reflecting mirror is applied as the reflecting means. The reflected light from the reflecting means is re-injected to EDF and acts as the pumping light, thus increasing the amplification gain for the L-band input light remarkably.Type: ApplicationFiled: April 6, 2001Publication date: January 10, 2002Applicant: MERCURY CORPORATIONInventors: Sang Woork Park, Kyu Haeng Lee, Sung Chil Jo, Seung Taek Kim, Dong Han Lee
