EXCITATION LIGHT SOURCE FOR RAMAN AMPLIFICATION, RAMAN AMPLIFIER, AND OPTICAL TRANSMISSION SYSTEM |
摘要 |
An excitation light source, for Raman amplification, includes a polarization beam splitter (PBS) for splitting a laser beam from an excitation laser into two polarization components, and a polarization beam combiner (PBC) for combining the two polarization components, and a time difference generator provided between PBS and PBC. The time difference generator generates a difference in propagation time between the two polarization components.
