A method of coupling optical waveguides comprising the steps of: (i) providing at least one pair of waveguides located such that (a) light radiation propagating through one of the waveguides will be at least partially coupled to a corresponding waveguide and, (b) these waveguides are separated by a gap of about 2 &mgr;m to about 500 &mgr;m long; the waveguides having positive dn/dT; (ii) filling the gap with a photo-polymerizable composition, the composition having dn/dT of &minus;2&times;10 /C to &minus;4&times;10 /C; (iii) providing simultaneous photo-radiation through said waveguides, wherein the photo-radiation photo-polymerizes the composition, thereby (a) creating a first region bridging between the waveguides, the first region having a first index of refraction, and (b) a second region encapsulating the first region, the second region having a second index of refraction, such that said first index of refraction of the first region is at least 0.1% higher than the second index of refraction; and (iv) curing the remaining composition, while retaining an index difference of at least 0.1% between the first region and the second region.

Waveguides and method of making them

A UV light-curable composition comprises: (a) a first component, said first component being UV light-polymerizable polymer having a first index of refraction; and (b) a second component, the second component being UV light-polymerizable monomer having a second index of refraction, the second index of refraction being higher than said first index of refraction; wherein the first component polymerizes slower upon exposure to UV radiation than the second component.

Photosensitive material suitable for making waveguides and method of making waveguides utilizing this photosensitive optical material

A method of making an in situ shaped optical element on the terminal end of an optical fiber, and the resultant optical fiber component for manipulating light entering or exiting the terminal end of an optical fiber. The in situ shaped optical element is preferably an inorganic-organic hybrid sol-gel material which is adhered to the terminal end of the optical fiber and shaped in place to define an optical element or surface.

Optical fiber component with shaped optical element and method of making same

A method of molding precision glass optical elements or lenses is disclosed. Precision molded glass molds are first provided which define a glass mold cavity having a predetermined desired size, shape and volume corresponding to the glass optical element. To facilitate formation of the glass optical elements, shaped and polished preforms are formed.

Method of molding glass optical elements

A method of forming precision glass molds suitable for molding glass optical elements or lenses is disclosed. The glass molds define first and second opposed optical molding surfaces. Each master is formed by defining a master cavity adapted to form a first glass mold. A quantity of glass mold material is disposed within such cavity and molded in conformation with said master. The molding surface of each such glass mold defines an optical surface to be subsequently formed on an optical element.
