Latest Patents

One of Mauro's latest patents is an optical fiber light tap. This invention describes a beamsplitter formed by positioning bevelled, parallel endfaces of two segments of optical fiber in coaxial alignment and in close proximity to each other. A suitable dielectric film, such as air, fills the gap between the endfaces. Light propagating into the tap from the first fiber segment is partially reflected and partially refracted at the bevelled endfaces. The refracted portion enters the second fiber segment, while the reflected portion leaves the tap and is detected by a photodetector. By choosing the proper angle for the bevelled endfaces, the tap can be made substantially mode independent. A greater degree of mode independence can be obtained by interposing a steady-state mode exciter between the light source and the beamsplitter. This tap is particularly useful for semiconductor junction laser stabilization by the feedback arrangement described, as the ratio of the intensity of the reflected portion to that of the refracted portion remains substantially constant. Additionally, a package assembly for use in the feedback arrangement is also described.

Another significant patent is a solid-state electrical switch employing electrochromic material. This switch exhibits high off/on resistance ratios and low insertion loss. An additional advantage is that the removal of the switching energy does not alter the status (off or on) of the switch. The active solid-state material in the switch is an electrochromic material, such as tungsten trioxide, which undergoes a transformation from insulator to metallic conductor upon the injection of certain ions.
