GUIDE TRANSITION DEVICE AND METHOD March 14, 2019

United States Patent Application 20190079243

Abstract
A guide transition device including a light source designed to generate a light beam, a light input port on a first plane and coupled to receive the light beam from the light source, a light output port on a second plane different than the first plane, the light output port designed to couple a received light beam to output equipment and plane shifting apparatus coupled to receive the light beam from the light input port on the first plane and to shift or transfer the light beam to the second plane. The plane shifting apparatus is coupled to transfer the light beam to the light output port on the second plane.

FIG. 1 is a top view of a PSM (phase shift modulation) layout with a single laser source divided into four inputs for four different modulators using a guide transition device (GTD) to couple the four inputs into four waveguides and then out to four fiber cables, according to the present invention;

FIG. 2 is a top view of a WDM (wavelength division multiplexing) layout with four different wavelength lasers coupled by four GTDs and then mux'd into one waveguide and out to a fiber cable, according to the present invention
