Tellurite photonic crystal fiber

We report the fabrication of a Tellurite photonic crystal fiber, and demonstrate its waveguiding properties. The measured minimum loss is 2.3 dB/m at a wavelength of 1055 nm. The fiber supports several modes, but in practice just the fundamental mode can be used. We have observed strong stimulated Raman scattering in a fiber with an effective area A(eff)= 21.2 mum(2), using sub-ns, similar to 1 muJ pump pulses at 1064 nm. (C) 2003 Optical Society of America.
