Abstract: An optical system includes a base, a plurality of optical fibers, and a plurality of optical components. The base has a fiber retention and alignment section and an optical coupling section. The fiber retention and alignment section have a plurality of alignment members, where each alignment member is configured to receive an optical fiber therein. The optical coupling section has an optical coupling block and includes a plurality of optical coupling elements, with each optical coupling element having an ellipsoidal reflecting surface defining a first focal point and a second focal point. The first focal surface is generally aligned with the first focal point. The second focal surface is generally aligned with the second focal point. Each optical fiber is positioned within one of the alignment members and adjacent one of the first focal surfaces. Each optical component is positioned adjacent one of the second focal surfaces.

Abstract: An optical system includes a base with a fiber retention and alignment section having at least one alignment member. An optical coupling section of the base has an optical coupling block and includes at least one optical coupling element with an ellipsoidal reflecting surface defining first and second focal points. First and second focal surface are generally aligned with the first and second focal points, respectively. An optical path extends through each optical coupling element and is aligned with one of the alignment members. An optical fiber is positioned within each alignment member adjacent a first focal surface and an optical component is optically aligned with each optical fiber and positioned adjacent one of the second focal surfaces.

Abstract: Circuits for converting an input current to an output voltage that employs a uniquely biased common-gate or common-base stage as a current buffer and a direct drive of the current buffer output into an impedance to convert the current signal to a voltage signal.
