    Abstract: An optical apparatus for circularizing a laser beam includes a bench having indentations thereon and optical elements provided in these indentations. A first optical element has a high numerical aperture. A second optical element collimates the beam output by the first optical element and is spaced from the first optical element. This spacing is determined in accordance with a location of the beam output by the first optical element at which the beam will be most circular. The indentation in which the second optical element is placed may be both vertically and horizontally displaced from the indentation in which the first optical element is placed.

    Abstract: A broadband diffractive diffuser contains at least three levels, with approximately a phase shift of .pi. between at least two of the at least three levels. Such a diffuser provides light with more than two phasor vectors at the zero order. The presence of the more than two phasor vectors reduces the zero order diffraction efficiency at non-design wavelength, increasing the usefulness of the diffuser at wavelengths other than the design wavelength. Preferably, the diffractive diffuser includes a plurality of regions, approximately 50% of an area of the plurality of regions presenting a phase shift of .pi. at a design wavelength, approximately 25% of the area of the plurality of regions presenting a phase shift of 2.pi. at the design wavelength, and approximately 25% of the area of the plurality of regions presenting a phase shift of 0 at the design wavelength. Such a diffractive diffuser may be formed by logical operations between two diffractive diffuser patterns, by adding two diffractive diffuser patterns, or by pixel-by-pixel scanning.

    Abstract: In accordance with the present invention, a BOE-corrected, off-axis image forming apparatus is disclosed. The apparatus has a first stage with a primary reflective element disposed to reflect light incident from an entrance pupil of the apparatus and form a real image at an intermediate image plane, and a second stage located off-axis with respect to the first stage. The second stage is defined by a secondary reflective and/or refractive assembly which re-images light from the intermediate image plane to a final image plane. A binary optical element (BOE), which has higher-order optical characteristics for providing aspheric correction but extremely low optical power, is provided in one of the stages for correcting aberrations introduced by the other optical elements in the apparatus. The BOE contributes no more than about 3% of the optical power provided by the stage which contains the BOE.

    Abstract: A waveguide to waveguide monitor includes an optics block between the two waveguides. The optics block couples light between the two waveguides and includes at least two parallel surfaces. The monitor also has an optical tap which creates a monitor beam.
