    Abstract: An optical component in the form of a right angled triangular prism having a first side, a second side orthogonal to the first side, and a third side generally inclined to the first and second sides to reflect optical radiation incoming from the first side towards the second side. The first and second sides have semi-reflecting surfaces acting as etalon surfaces providing an interferometric pattern. The optical transmittance between the first and the second sides is wavelength dependent and the radiation exiting the second side of the component is rotated 90 degrees to the radiation entering the first side.

    Abstract: An optical assembly for use in an optical telecommunications system and method for aligning the optical assembly. The assembly uses a pair of ball bearings to support an optical fibre on a baseplate. The optical fibre is aligned with respect to an optical device and then the first ball bearing is inserted and welded in place. The fibre alignment is then fine tuned and the second ball bearing is inserted and welded in place, thereby providing a simpler and more accurate method of aligning an optical fibre to an optical device.

    Abstract: An apparatus for determining the wavelength of light emitted by, for example, a laser, includes three photodiodes. One photodiode receives a proportion of the light redirected from the main optical path by a beam splitter. A second photodiode receives a proportion of the light redirected from the main optical path by the beam splitter and passing through a broadband filter. A third photodiode receives light that has been caused to interfere by an interferometric device. The ratio of the light intensities at the first and second photodiodes provide a coarse determination of wavelength, when compared to a lookup table, and the ratio of the light intensities at the first and third photodiodes provide a more exact determination of the wavelength.
