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.

Abstract: An hermetically sealed monolithic photonic integrated circuit (PIC) including optical components and multiple optical and electrical inputs/outputs. The integrated circuit including a semiconductor/metal base with sensitive semiconductor/polymer electrical and optical components formed therein. The electrical and optical components having multiple optical and electrical inputs, multiple optical and electrical outputs, and/or multiple optical and electrical inputs and outputs. A semiconductor/metal basic lid is sealed to the semiconductor/metal base by metallization so as to form a chamber including the sensitive semiconductor/polymer electrical and optical components and hermetically sealing the chamber and the sensitive components from the ambient in a basic hermetic capsule with multiple optical pathways coupling multiple optical fibers to the optical components sealed within the chamber.
