Abstract:
1. A monolithic Mach-Zehnder Interferometer (MZI) for photon beam-splitting, said MZI comprising: a complimentary pair of right-isosceles triangular prisms configurable to physically join together along associated hypotenuse surfaces that form a beam-splitter interface, thereby producing a rectangular prism having a square cross-section with four outer side surfaces; a plurality of trombone reflector units, each reflector unit forming a right-isosceles mirror that rigidly faces a corresponding surface of said four outer side surfaces of said rectangular prism; and a plurality of spacers, wherein each spacer is correspondingly disposed between said reflector unit and said corresponding surface of said rectangular prism to provide a corresponding space, each said space being receptive to a probe inserted therein.
