    摘要: A low noise optical amplifier used in an optical communication system includes optical amplifying elements for amplifying optical signals of a specific wavelength(&lgr;) incident from their ends(F1,F2) and endowing phase difference between ASEs, optical diverging means to interfere the amplified optical signals and the ASEs output from both ends(F1,F2), first path of length(L1) to optically connect the one end(F1) to first gate(D1) of the optical diverging means, and second path of length(L2) to optically connect the other end(F2) to second gate(D2) of the optical diverging means. The first and second paths are designed with distance(L1-L2) so that the amplified optical signal causes reinforcing interference at the third gate(D3) and destructive interference at the fourth gate(D4), and the ASE causes destructive interference at the third gate(D3) and reinforcing interference at fourth gate(D4).
