An electro-optical subassembly generally includes a base supporting at least one lead and a lens unit having a lens. The lead supports an electro-optical component. The lens unit is through transmission laser welded to the base such that the lens is aligned with the electro-optical component.

Electro-optical subassemblies and method for assembly thereof

An optical element includes a light absorbing medium formed of a transparent material and light absorbing elements encapsulated within the transparent material. The light absorbing elements have an ultraviolet (UV) light-dependent absorption characteristic and UV light is applied to the light absorbing medium to change the attenuation of the light absorbing medium to a desired attenuation. UV light is applied to the light absorbing medium in a controlled manner to change the attenuation of the light absorbing medium from an initial attenuation to the desired attenuation. The application of UV light to the light absorbing medium can cause the light absorbing elements encapsulated within the light absorbing medium to degrade such that the amount of light absorbed by the light absorbing medium is reduced. Reducing the amount of light that is absorbed effectively reduces the attenuation of the light absorbing medium.

UV adjustable optical attenuator

An opto-electronic housing and an opto-electronic assembly. The housing includes an enclosure defining a cavity. An opening through a wall of the enclosure is adapted to receive a substrate. A mount projects into the cavity opposite the opening. The mount is adapted to support an opto-electronic device. Adjacent the mount is an optically transmissive region in a wall of the enclosure. An opto-electronic assembly also includes a substrate disposed in the opening and an opto-electronic device supported by the mount.

Opto-electronic housing and optical assembly

A method for controlling the attenuation of an optical element. A base material, such as a resin, is selected from which to fabricate the optical element. The base material has an intrinsic attenuation or intrinsic absorption spectrum. A predetermined concentration of a first type of dye molecule is then added to the base material to vary the intrinsic attenuation of the base material to achieve a predetermined absorption spectrum.
