A photonic crystal fiber splice with a standard single mode fiber

We report on the optimization of a fused splice between a photonic crystal fiber (PCF) with a standard single mode fiber (SMF) made by the filament fusion with continuous laser illumination. For the SMF 28 connection with a PCF having a similar mode field diameter splice losses are lower than 0.40 dB in comparison with the reported dependences in a spectral range of 1.51-1.63um. Based on the results obtained two aspects of splice are discussed: the mentioned above wavelength dependences as well as an observed nonreciprocal phenomenon according to light propagation through the splice. The discussed data have shown that such a SMF-PCF splice is suitable for the construction of a patch cord for measurement devices. Full Text: PDF References: B.
