摘要： An optical fiber amplifier has an optical amplification portion, pumping light source, and optical circulator portion. The optical amplification portion has a signal input port, signal output port, and two erbium-doped optical fibers. These optical fibers are connected in series between the signal input port and the signal output port. The pumping light source is optically coupled to the optical fibers through an optical coupler to supply pumping light to the optical fibers. The optical circulator portion supplies backward ASE light obtained from the signal input port of the optical amplification portion to the signal output port thereof. With this arrangement, not only forward ASE light but also backward ASE light can be supplied to the optical amplification portion. There is no additional optical fiber, which is not pumped by light for the light source, to use both ASE light components for optical amplification.

摘要： A diffraction grating portion (12) is formed in an optical fiber (10), having a diameter of 125 .mu.m and serving to transmit light, along its optical axis. The optical fiber is concentrically surrounded by a lower coating portion (14) having an outer diameter of 300 .mu.m and consisting of a silicone resin. The lower coating portion is concentrically surrounded by a coating portion (16) having an outer diameter of 900 .mu.m and consisting of a liquid crystal polymer, e.g., polyester amide. The coating portion is further surrounded by an outermost coating portion (18) having an outer diameter of 1 mm and consisting of a UV curing resin colored for identification. Both the optical fiber (10) and the lower coating portion (14) have positive thermal expansion coefficients. In contrast to this, the coating portion (16) consisting of the liquid crystal polymer has a negative thermal expansion coefficient.
