Multi-wavelength, continuous wavefibre Raman ring laser operating at 1.55 µm

Abstract

A four wavelength, continuous wave, fibre Raman ring laser has been demonstrated at room temperature using fibre Bragg gratings as the wavelength-selective elements with applications as a multi-wavelength source for optical fibre telecommunications. Channel spacings were ~5 nm between 1551.6 and 1565.1 nm with 14.9 dBm total output power.
