    摘要： A sub-wavelength anti-reflective diffractive structure is incorporated with a base diffractive structure having a small period to form a high efficiency diffractive structure. In the high efficiency diffractive structure, the anti-reflective structure and/or the base diffractive structure are altered from their ideal solo structure to provide both the desired performance and minimize reflections.

    摘要： Gray scale masks used to create optical elements are formed. Desired gray scale patterns may be created by varying a transmission across a mask, e.g., by varying the thickness of a light absorbing layer. Such variations in thickness may be created using multiple binary masks. Desired gray scale patterns may also be created on a computer using available software and then imaged onto film or a glass film plate. Direct contact or proximity printing is then used to transfer the true gray scale pattern onto a photoresist layer. The photoresist layer is then etched, thereby forming the desired pattern therein. All portions of the desired pattern are simultaneously formed in the photoresist layer. The etched photoresist layer is then used to photolithographically fabricate either the optical element itself or a master element to be used in injection molding or other replication techniques. The gray scale mask itself may be used repeatedly to generate photoresist layers.

    摘要： An optical coupler reduces differential mode delay in a fiber by reducing an amount of light incident on the fiber in a region in which the refractive index is not well controlled. This region of the fiber is typically in the center of the fiber. The optical coupler directs light away from the this region and/or provides a high angle of incidence to any light on this region. A diffuser may be used to reduce sensitivity of the coupler to any fluctutations in the output of the light source. The optical coupler does not need to be offset from the center of the multi-mode coupler. A phase function of an azimuthal mode of the fiber may be imposed on the light beam so that a substantial null on axis is maintained even after propogation of the light beam beyond the depth of focus of the coupler. A diffractive element generating a beam which propogates in a spiral fashion along an axis allows the shape of the beam to be maintained for longer than a depth of focus of the diffractive element.

    摘要： An integrated optical apparatus includes an optically transparent substrate with a light source and a detector mounted adjacent thereto. The substrate includes an optical element in a transmit path from the light source to a remote target. The optical element splits the light into more than one beam. A detector receives beams reflected by the target. All optical elements needed to create the more then one beam, direct the more than one beam onto the target and direct the more than one beam from the target to the detector are on the substrate and/or any structure bonded to the substrate. Preferably, the optical element provides sufficient separation between the more than one beam such that each beam is delivered to a unique respective light detecting element of the detector. The return path from the remote target to the detector may include an optical element for each beam or no optical elements. An additional substrate may be included and bonded to the substrate. The active elements may be bonded to a bottom surface of the substrate, either directly or via spacer blocks, or may be provided on a support substrate, which is then bonded, either directly or via spacer blocks, to the substrate.
