    Abstract: Multicore optical fibers (10) that include between two and ten multimode cores (30a - 30d) surrounded by a cladding matrix (20) and symmetrically arranged about a fiber axis (AF) are disclosed, with no core running along the fiber axis. The cores include a trench (34) to stabilize delays of the higher order modes, which tend to propagate faster than do the central modes due to the amount of power at the core-clad interface. The trench also suppresses crosstalk and power leakage. The core configuration promotes efficient optical alignment and optical coupling with other multicore optical fibers or light sources, such as VSCEL and silicon-photonics light sources.

    Abstract: An optical package includes a semiconductor laser, a wavelength conversion device and a MEMS-actuated mirror oriented on a base module to form a folded optical pathway between an output of the semiconductor laser and an input of the wavelength conversion device. An optical assembly is located in a mechanical positioning device and the mechanical positioning device is disposed on the base module along the optical pathway such that the beam of the semiconductor laser passes through the optical assembly, is reflected by the MEMS-actuated mirror back through the optical assembly and into the waveguide portion of the wavelength conversion device. The MEMS-actuated mirror is operable to scan the beam of the semiconductor laser over the input of the wavelength conversion device. The optical assembly may be adjusted along the optical pathway with the mechanical positioning device to focus the beam into the waveguide portion of the wavelength conversion device.

    Abstract: Assemblies, optical connectors, and methods for bonding optical fibers (110) to a substrate (100) using a laser beam (120) are disclosed. In one embodiment, a method of bonding an optical fiber (110) to a substrate (100) includes directing a laser beam (120) into the optical fiber (110) disposed on a surface (102) of the substrate (100), wherein the optical fiber (110) has a curved surface (111) and the curved surface (111) of the optical fiber focuses the laser beam (120) to a diameter that is smaller than a diameter of the laser beam as it enters the optical fiber. The method further includes melting, using the laser beam (120), a material of the substrate (110) at a bond area (112) between the optical fiber (110) and the surface (102) of the substrate (100) such that the optical fiber (110) is bonded to the surface (102) of the substrate (100).
