1-mum waveband, 12.5-Gbps transmission over a 1.5-km single-mode holey-fiber is demonstrated with clear eye-openings. A wavelength tunable single-mode selected quantum-dot optical frequency-comb laser is used as the optical-source potentially capable of wavelength division multiplexing (WDM).
We analyze optical properties of all-silica photonic bandgap fibers with an ultra low ratio of the cladding rods diameter to the center-to-center distance of the rods. Optical properties similar to those of LMA holey fibers are revealed both numerically and experimentally.
We report on the design, fabrication and characterization of hollow-core photonic crystal fiber with two robust bandgaps that bridge the benchmark laser wavelengths 1064 nm with 1550 nm, and 1064 nm with 780 nm.
Writing Bragg gratings inside the core of a photonic crystal fiber (PCF), we demonstrate an all-fiber Raman laser fully made with a highly nonlinear PCF. The laser delivers an output power of 4 Watt.
