Protective housing for an integrated optical component

An optical waveguide component, with a pigtail attached thereto, is disclosed in which a portion of a surface of the component is bevelled and a portion of the endface of the pigtail is bevelled. The bevelled portion of the pigtail endface is oriented to be substantially parallel to the bevelled portion of the component surface or is oriented to be open with respect to the component surface. The pigtail endface can be continuously bevelled to form a substantially conical shape on the pigtail endface, wherein the substantially conical shape is offset from the optical axis of the pigtail.

Planar optical waveguides with low back reflection pigtailing

This invention is directed to the production of glass-plastic lenses consisting of a thin glass element bonded to a relatively thick transparent lens or lens preform made of poly(diethylene glycol)bis(allyl carbonate) by a transparent thermoset, polyurethane adhesive layer of optical quality having an elongation at rupture of at least 200% and an elastic modulus in the range of 0.13-10 MPa and at 100% elongation.
