    Abstract: The optical fibre microlens includes a single-mode optical fibre having a core and a cladding, a longitudinal fibre axis extending through the core. A wedge-shaped microlens is provided on one end of the fibre, the microlens including a first pair of surfaces that intersect at a line that bisects the fibre core. A second pair of surfaces intersect the first pair of surfaces, the slopes of the first and second pairs of surfaces being theta and phi , where phi is greater than theta . The slopes of the first and second pairs of surfaces are measured with respect to a plane perpendicular to the longitudinal fibre axis.

    Abstract: Se describe un método y aparato para inscribir una rejilla de Bragg en una guía de ondas opticas fotosensible. El novedoso método consta de un interferometro que tiene componentes de reunion y direccion de la luz ajustables con precision. Se usa una máscara de fase iluminada con la luz ultravioleta como la fuente novedosa del interferometro. La ajustabilidad del interferometro permite la inscripcion de rejillas de Bragg para longitudes de onda de filtracion en la escala de Bragg para longitudes de onda de filtracion en la escala de 1275 nm a 1575 nm mientras se ajustan los elementos apropiados del interferometro por solamente +/-0.75 degree cada uno.

    Abstract: A method and apparatus for writing a Bragg grating in a photosensitive optical waveguide is disclosed. The novel method comprises an interferometer having precisely adjustable light collecting and directing components. A phase mask illuminated with ultraviolet light is used as the interferometer light source. The adjustability of the interferometer allows the writing of Bragg gratings for filtering wavelengths in the range 1275 nm to 1575 nm while adjusting the appropriate interferometer elements by only +/- 0.75.degree. each.
