"cheap/ flexible single-mode waveguides couple light from external laser/ distribute within system, compatible with electrical circuits... low polarization-dependent loss/ differential group delay, minimizing distortions... consistent insertion loss/ mode field dimensions between waveguides, so are energy-efficient optical interconnects... >20 dB polarization extinction ratio across all CWDM4 wavelengths, no power degradation even after 6 hours, minimal heating concerns... high-performance computing, data centers"
