Multi-wavelength optical fiber

摘要

The invention features a fiber that includes an optical fiber ( 110 ) containing a gain medium having a Raman active material with a Raman gain spectrum. The optical fiber is configured to receive energy at a wavelength lambda_p. The fiber also includes at least three pairs of reflectors ( 120, 125, 150, 130, 160 ) disposed in the optical fiber. Each pair of reflectors forms a resonance cavity ( 140 ) with a resonance frequency.
