摘要: Grating built-in type optical fiber couplers and optical amplifiers form a multiplexer for efficiently effecting multiplex separation of a specific wavelength without using an optical circulator. A function to add a signal of specific wavelength efficiently can be realized. Additionally, the device is inexpensive.
