ABSTRACT:
A waveguide to waveguide monitor includes an optics block between the two waveguides. The optics block couples light between the two waveguides and includes at least two parallel surfaces. The monitor also has an optical tap which creates a monitor beam. The optics block may be flush with the endfaces of the waveguides, even if the endfaces are angled. At least two optical elements needed to couple the light between the two optical waveguides and direct the monitor beam on a detector are on the at least two parallel surfaces of the optics block and any surfaces secured thereto.
