With an MMCDF core diameter of ∼15.5 μm that matches the SMF, we obtained coupling efficiencies of 60.3% to 87.5% in the entire transmission spectral range of 1300 to 1600 nm. The high coupling efficiency (or low insertion loss) makes it possible for the employment of the MMCDF as an inline ultra-broadband optical amplifier in an optical link for the entire transmission spectral range. © 2008 Optical Society of America. |
