Abstract: An optical fiber cladding optical filter includes an elongated capillary tube including an inner surface positioned surrounding an elongated optical fiber proximate or adjacent an exterior surface of the optical fiber and an outer surface positioned spaced from the exterior surface of the optical fiber. A grating formed on the outer surface of the elongated capillary tube aids in suppressing evanescent laser light that exits the optical fiber transverse to a longitudinal axis of the optical fiber. The elongated optical fiber and surrounding elongated capillary tube can include one or more curves along a length thereof to aid in the removal of one or more higher order laser modes as evanescent laser light that exits the optical fiber. The one or more curves can be received in a container to prevent or avoid evanescent laser exiting the optical fiber from propagating into an ambient environment.

Abstract: An intracavity frequency-doubling laser device includes a first mirror and a second mirror defining a resonance cavity, a gain media to produce a first lasing light in response to an external pump beam received from outside the cavity, a nonlinear frequency-doubling optical element to generate a second lasing light in response to the first lasing light, a birefringent waveplate to control phase properties of the first and second lasing lights, and a fused quartz element positioned at the exit of the resonance cavity. The second mirror is formed as a relatively thick film on the fused quartz and is controlled to create an output beam of the second lasing light with great accuracy. The four components within the resonance cavity are positioned back-to-back and held in place using an optical glue (forming a compact, miniaturized laser device).

Abstract: A proposed fabrication technique for a polarization-absorbing wire grid polarizer avoids the need to etch through the multilayer stack of materials to form the grid structure. Initial reflective metal and dielectric buffer layers are patterned and etched in a conventional manner to create the desired grid topology. A small-angle coating process is then used to complete the fabrication process by first coating the top surface of the patterned dielectric with a polarization-absorbing metal. A second coating process is used to cover the created metal coating with a dielectric cladding material. Maintaining a small angle of incidence between the coating source and the wire grid structure ensures that top portions of the grid are suitably covered to create the desired multilayer wire configuration.
