Abstract: A lens assembly for an optical fiber includes an optical gap structure and a multi-mode optical fiber. The optical gap structure has first and second ends and a length measured therebetween. The first end of the optical gap structure is configured to attach to an end of a single-mode optical fiber.

Abstract: A grating coupler reflector (retro reflector) is formed within a photonics chip and includes a vertical scattering region, an optical waveguide, and a reflector. The optical waveguide is optically coupled to the vertical scattering region. The reflector is positioned at an end of the optical waveguide. The reflector is configured to reflect light that propagates through the optical waveguide from the vertical scattering region back toward the vertical scattering region. The location of the grating coupler reflector on the photonics chip is determinable by scanning a light emitting active optical fiber over the chip and detecting when light is reflected back into the active optical fiber from the grating coupler reflector. The determined location of the grating coupler reflector on the photonics chip is usable as a reference location for aligning optical fiber(s) to corresponding optical grating couplers on the photonics chip.

Abstract: A first reflecting region is positioned at an end of an optical fiber and includes a polarization-sensitive reflector configured to selectively reflect a first polarization of light emanating from the optical fiber into a first reflected beam and transmit light that is not of the first polarization. The first reflected beam is directed toward a first optical grating coupler on a chip. A spacer layer is disposed on the first reflecting region such that light transmitted from the first reflecting region enters and passes through the spacer layer. A second reflecting region is disposed on the spacer layer and is configured to reflect light that is incident upon the second reflecting region into a second reflected beam directed toward a second optical grating coupler on the chip. A thickness of the spacer layer is set to control a separation distance between the first reflected beam and the second reflected beam.

Abstract: A beam steering structure includes an alignment structure shaped to receive and align an optical fiber such that an axis of a core of the optical fiber is oriented in a first direction. The beam steering structure includes an end portion having an angled optical surface oriented at a non-zero angle relative to the first direction. The end portion is shaped and positioned so that light propagating along the first direction from the optical fiber passes through the end portion to reach the angled optical surface. A reflecting system is positioned on the angled optical surface across the first direction. The reflecting system is configured to reflect incident light propagating along the first direction into a first reflected beam of a first polarization and a second reflected beam of a second polarization. The first and second reflected beams are directed into first and second optical communication channels, respectively.

Abstract: An optical fiber comprises core and cladding regions configured to guide the propagation of light (or radiation) in the core region. The cladding region includes a periodic structure configured to produce light guiding by bandgap confinement. In order to suppress higher order odes (HOMs) in the core region, the cladding region includes at least one perturbation region configured so that a mode of the cladding region is resonant with a HOM of the core region. In a preferred embodiment of my invention, the perturbation region is configured so that the fundamental mode of the cladding region is resonant with a HOM of the core region.

Abstract: An optical fiber that exhibits reduced mode distortions as the fiber is bent is formed by properly defining its refractive index profile during fabrication. The as-fabricated profile is defined as a “pre-distorted” profile that takes into account the gradient introduced by bending the fiber. A parabolic index profile is one exemplary bend-resistant profile that exhibits a quadratic form. A raised-cone index is another profile that may be used as the “as-fabricated” profile. In any properly configured form, factors such as bend loss and mode distortion are significantly reduced, since the profile undergoes a shift of essentially constant gradient as a bend is introduced. The resultant effective area of the inventive fiber is substantially improved over state-of-the-art fiber that is subjected to bending during installation. The as-fabricated profile may be incorporated into various types of fibers (birefringent, photonic bandgap, etc.), and is particularly well-suited for use in a fiber amplifier arrangement.

Abstract: An in-line, distributed optical fiber filter comprises a core region with a raised refractive index (with respect to the surrounding cladding material) so as to allow for total internal reflection (TIR) of the desired transmission wavelength(s). One or more raised index features are formed within the cladding region and are configured so as to result in mode mixing between the cladding mode and core mode at determined wavelength(s) to be removed by filtering. The parameters associated with determining the proper core specifications and cladding specifications can be separately determined to provide for enhanced performance in terms of both filtering unwanted signals and propagation of desired communication signals.
