Abstract:
1. A method for installing an optical tap into an optical waveguide formed in a substrate comprising: obtaining a substrate having at least one optical waveguide formed therein, wherein the at least one optical waveguide is configured to carry a coherent beam of light; cutting a transverse groove having a front plane and a back plane into the at least one optical waveguide, wherein the back plane has an oblique angle of incidence relative to the beam of light; inserting a pre-fabricated beamsplitter into the groove such that the beamsplitter is substantially positioned at the oblique angle of incidence relative to the beam of light to enable a given predetermined portion of the beam of light to be directed out of the waveguide and to enable another predetermined portion of the beam of light to be directed through the waveguide; cutting the at least one transverse groove that is V-shaped, and wherein the front plane and the back plane of the at least one transverse groove come together to form a registering corner at the bottom of the groove; and inserting the beamsplitter into the at least one transverse groove until it registers against the registering corner at the bottom of the groove.
