摘要: A low noise optical amplifier used in an communication system includes amplifying elements for signals of a specific wavelength (μ) incident from their ends (F1, F2) and endowing phase difference between ASEs, diverging means to interfere the amplified ASEs output both F2), first path length (L1) optically connect one end (F1) gate (D1) means, second (L2) other (F2) (D2) means. The paths are designed with distance (L1-L?2) so that signal causes reinforcing interference at third (D3) destructive fourth (D4), ASE (D4).
