A new fabrication method for a laser-to-single-mode-fiber coupling module has been developed, where the first spherical (or ball) lens of a double confocal lens system is affixed by a new UV (ultraviolet light) curable adhesive. Temperature characteristics and preliminary reliability test results confirmed that the module is sufficiently stable for usage in fiber-optic communication systems and other applications.
