✦ Synopsis

Mechanical reliability of optical fibers fed to a stainless steel (AlSl 303) package was investigated to achieve a hermetically sealed LiNbO 3 modulator device for optical communication systems. The fiber jacketed with an ultraviolet radiation-cured resin (acrylate) and a hytrel loose tube was sealed to ensure high mechanical stability during temperature fluctuations. The sealing of the fibers was completed using a soldering technique. The assembled devices were exposed under mechanical tests of Bellcore's TR-NWT-000468 requirement, and no deterioration was observed in the installed fibers. The proposed package structure can achieve a fiber-break-free LiNbO 3 device.
