Claim of US Patent No. 10,509,164

1. A guide transition device comprising:a semiconductor platform defining a first plane and including a monolithic semiconductor laser designed to generate a light beam into the first plane;
a light input port on the first plane, the light input port being coupled to receive the light beam from the monolithic semiconductor laser;
a polymer second plane formed on the semiconductor platform different than the first plane and defining a polymer waveguide;
a polymer waveguide light output port on the polymer second plane, the light output port designed to couple a received light beam to output equipment, the polymer waveguide includes a lower cladding layer, a core, and an upper cladding layer, a first end of the lower cladding layer, the core, and the upper cladding layer being cut at an angle to define the second angular deflection surface, a second end of the lower cladding layer, the core, and the upper cladding layer defining the light output port, and at least one protection layer between the lower cladding layer and the core, and at least one protection layer between the upper cladding layer and the core; and
plane shifting apparatus including a first angular deflection surface in the first plane and a second angular deflection surface in the polymer second plane, the plane shifting apparatus being 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 polymer waveguide of the polymer second plane, the plane shifting apparatus being coupled to transfer the light beam to the polymer waveguide light output port on the second plane.
