An optical fiber assembly comprises an optical fiber having a forward end, a ferrule supporting the optical fiber, a beam expanding element aligned with the forward end of the optical fiber, and a thermal expansion compensation element adjacent the optical fiber to compensate for thermal expansion differences between the optical fiber and the ferrule.

An optical fiber assembly includes a ferrule body with a plurality of optical fibers and an end of each optical fiber positioned adjacent the front face of the ferrule body. A beam-expanding element is positioned adjacent the front face of the ferrule body including a lens array aligned with the optical fibers. The lens array is spaced from the optical fibers by a predetermined distance to form a gap with an index-matched medium within the gap. A method of manufacturing the optical fiber assembly is also provided.

A connector incorporating a module, in which an incorporated electrical component may be cooled efficiently and reliably, is provided. A transmission apparatus disposed inside a main body cover of a module-incorporating connector is provided with a ceramic board at which an electrical component and such are mounted. A metal cover touches an upper face of the electrical component. A portion of the metal cover is disposed in an insertion portion of the main body cover. Heat generated by the electrical component is propagated via the metal cover to the insertion portion of a first cover member. When the module-incorporating connector is connected to a socket of a device, the insertion portion is disposed inside an exterior case, in which temperature is controlled by an air conditioner, and cooling is performed reliably and efficiently.

A tapered waveguide optical mode transformer () includes a tapered core formed on a planar substrate structure (). To vertically taper the core (), steps () are etched into the top surface of the core. The steps have depths and lengths along the optical axis of tapered waveguide that are selected to transform the optical mode characteristics of a desired optical fiber to the optical mode characteristics of a desired planar waveguide. The core can also be tapered horizontally to form a 2-D tapered waveguide. The tapered waveguide can be integrally included in planar lightwave circuits (PLCs) to reduce light coupling losses between optical fibers and the PLC waveguides.
