Apparatus for adjusting channel width of multi-channel fiber amplifier light source |
摘要 |
An apparatus for adjusting the channel width of a multi-channel fiber amplifier light source, including an erbium-doped optical fiber amplifier constructed to generate a spontaneously emitted, amplified noise beam under a condition that no optical signal is applied thereto, the amplifier being used as a light source for wavelength division multiplexing, namely, a fiber amplifier light source. By the angle-turned Fabry-Perot etalon filter and the fiber-optic beam expander, the channel width can be easily controlled without affecting the free spectral range and the power of output light.
