SM and PM Pigtailed Small Mode Field Diameter Fiber Arrays

Recently there has been significant progress in integrated optical waveguide technologies including silicon photonics. Most of those state of arts waveguide technologies require small core fibers (small mode field diameter (MFD) fiber) or lensed fibers due to their small waveguide core sizes. For many practical device applications, non-lensed small core fibers are preferred since ease in the fiber alignment and robust fiber support.



EpiPhotonics has developed small core fiber array pigtails based on PLZT optical waveguide technology which utilized the small core fibers. The small core fiber array pigtails have minimum splicing loss (< 0.1 dB), pitch accuracy better than 0.5 um, and mode field diameters (MFD) ranging from 3.2 um to 7.7 um which match most advanced high-contrast waveguide technologies. Polarization maintaining fiber with small MFD are also available.
