Abstract: Described herein are methods, systems, and apparatuses to utilize shielding regions formed in photonic integrated circuits (PICs). Portions of layers of a PIC are selectively removed, and optionally, replaced with another material. These regions are formed to block stray light from interacting with optical components of the PIC, and therefore can prevent optical crosstalk and/or noise. Metal or another absorption/reflective material can be deposited in the place of the removed layer portions of the PIC to absorb or reflect light. Additionally, by depositing metal, RF isolation can be achieved by forming a ground plane, by forming a ground trace that shields a signal trace in an RF transmission line, or by placing a conductor which terminates electric fields between sensitive RF receivers and adjacent RF elements. Additionally the process operations required to perform isolation can also be used to change the thermal conductivity of devices and regions on a PIC.

Abstract: A technique is described for terminating an optical fiber with low backreflection. At a selected end of the optical fiber segment, an endface is formed at a selected angle relative to the fiber axis. A suitable material is deposited onto the angled endface to form an angled reflective surface. The angled reflective surface is configured such that light propagating along the waveguide to the selected end of the optical fiber segment is reflected back into the optical fiber segment at an angle that prevents coupling of the reflected light into the fiber core. The reflected light is dissipated along the length of the fiber segment.
