Abstract: A system includes an optical source, an integrated circuit, an optical fiber, and a polarization controller. The optical source is arranged emit an optical signal. The integrated circuit includes a mirror. The optical fiber carries the optical signal from the optical source to the integrated circuit. The mirror reflects a transverse magnetic component of the optical signal through the optical fiber to the optical source. The polarization controller adjusts, based on the transverse magnetic component, the optical signal emitted from the optical source such that the transverse magnetic component is reduced.

Abstract: Techniques for aligning each of a plurality of optical fibers for coupling to a photonic integrated circuit (PIC). Transmission is detected from each respective optical fiber to the PIC using a probe, and the respective optical fiber is aligned based on the detected transmission. Each of the plurality of optical fibers is coupled to the PIC using at least one of: (i) laser splicing, (ii) laser spot welding, or (iii) arc welding,

Abstract: Techniques are provided for radiation-induced birefringence in a Polarization-Maintaining Fiber (PMF). In one example, a fiber is obtained. At least one local volume of the fiber is irradiated to induce an end-to-end birefringence in the fiber. Based on the end-to-end birefringence induced in the fiber, a PMF is produced.

Abstract: Aspects described herein include an apparatus supporting optical alignment with one or more optical waveguides optically exposed along an edge of a photonic integrated circuit (IC). The apparatus comprises a frame body comprising an upper portion defining a reference surface, and a lateral portion defining an interface for an optical connector connected with one or more optical fibers. The lateral portion comprises one or more optical components defining an optical path through the lateral portion. The one or more optical components are arranged relative to the reference surface such that the one or more optical components align with (i) the one or more optical waveguides along at least one dimension when the reference surface contacts a top surface of an anchor IC, and with (ii) the one or more optical fibers when the optical connector is connected at the interface.
