Abstract
An integrated lens with integrated functional optical surfaces for use in optical communication is disclosed. The integrated lens includes first and second cavities and a fiber adapter. The device also includes integrated first and second lenses. The first cavity houses one or more optical transmitting and/or receiving devices. The second cavity has a first optical surface and an optional second optical surface. The fiber adapter has the second lens. The integrated lens enables a small size, a light weight, high coupling and a high transmission efficiency, and can be produced by injection molding using a single mold. The integrated lens is applicable to optical signal coupling, fiber connections, optical modules, and optical or optoelectronic communication.
