BROADBAND LIGHT SOURCE USING A FABRY-PEROT FILTER

摘要

A broadband light source using a Fabry-Perot filter comprises: an eribium doped fibre (eribium doped optical fibre); a first optical coupler for coupling a first pump beam to the eribium doped fibre; and Fabry-Perot unit which is connected to the eribium doped fibre and splits input signal light into specific wavelengths, and reflects the split signal light of specific wavelengths and transmits the same to the eribium doped fibre.
