Abstract : An apparatus and method provides an optically aligned connector for at least one optical fiber. An optically excited fiber is brought to the close proximity of the lens and suitably micropositioned to a location where a maximum light intensity is monitored by a detector optically coupled to the excited fiber. When the fiber is positioned so that a maximum light intensity is monitored by a detector optically coupled to the excited fiber. When the fiber is positioned so that a maximum reflected intensity is monitored it is secured in place by, for example, a UV cureable adhesive. Mechanically indexing mating connector plates assure that an optical alignment from one fiber through its lens to another lens and onto another fiber is created. Multiple optical couplings between several pairs of fiber-lenses can simultaneously be created between a pair of appropriately designed connector plates. Optionally, appropriately machined collars held between single or multifibered connector plates are filled with an acceptable index matching fluid to assure suitable optical coupling.
