Cq. Xu et al., WAVELENGTH CONVERSIONS BETWEEN THE 2 SILICA FIBER LOSS WINDOWS AT 1.31 AND 1.55-MU-M USING DIFFERENCE-FREQUENCY-GENERATION, Electronics Letters, 30(25), 1994, pp. 2168-2169
Wavelength conversions between the two silica fibre loss windows at 1.
55 and 1.31 mu m have been demonstrated, for the first time, using dif
ference Frequency generation (DFG) in a periodically domain-inverted L
iNbO3 channel waveguide. The conversion efficiency, which is proportio
nal to pump light power, is -31dB for a pump light power of only 3.6mW
