Multi-wavelength fiber laser generation by using optical wavelength conversion

Abstract

A multi-wavelength fiber laser source is proposed and demonstrated by using simple, efficient wavelength conversion of a multi-wavelength Brillouin fiber laser (MBFL) assisted by fourwave mixing (FWM) processes. The MBFL is generated by emitting a Brillouin pump (BP) at the wavelength 1530 nm into a dispersion compensating fiber (DCF) of length 7.7 km in a ring cavity. By using the MBFL and a tunable laser source (TLS) as a FWM pump, both amplified through an erbium-doped amplifier and injected into a 100 m long highly nonlinear fiber (HNLF), two bundles of multi-wavelength fiber lasers are operated by degenerate FWM processes. When the TLS is set in the L band wavelength region, the two bundles of multiwavelength fiber lasers are generated simultaneously in the S and U band wavelength regions.

Studies on output characteristics of stable dual-wavelength ytterbium-doped photonic crystal fiber laser

“…Multi-wavelength laser operations around 1550 nm have been realized in erbium-doped fiber lasers by utilizing Mach-Zehnder comb filter [8] or Fabry-Perot filter [9], fiber Bragg grating (FBG) cavities [10][11][12][13], four-wave-mixing effect in high nonlinear fiber [14][15][16] and nonlinear polarization rotation [17].…”
