摘要： A device includes an optic in an at least partially rigid scaffold. The scaffold is permeated, at least temporarily during a writing process, by writable media. The optic may be written into a writable volume in the scaffold defined by the writable media. The optic may be written by exposing the writable media to incident light to cause a material property change in the writable media within the writable volume.

摘要： Objects and/or grouped emitters are anti-symmetrically excited. The anti-symmetric radiation emitted by the objects generate an interference pattern with a node in the spacing between the objects. The spacing may be sub-wavelength and/or below a resolution limit for the emitted radiation. Samples within the spacing may be detected via distortion to the inference pattern and visualized (including sub-resolution limit features) either directly or through reconstruction analysis from the interference pattern.

摘要： A high efficiency grating coupler design includes a grating region formed of a first material on an optics substrate. A side reflector formed of the first material is disposed on the optics substrate adjacent the grating region. A high contrast overlay is on the grating region, but is not disposed on the side reflector. The grating region includes teeth formed of the first material and the high contrast overlay, wherein the teeth have independently apodized fill factor, etch depth, and heights The first material and a material of the high contrast overlay can be selected to correspond to a particular laser type, wavelength of the laser, properties of the laser beam, and material of the laser. In addition, the teeth of the grating region, along with the side reflector teeth, can be apodized for optimized optical coupling efficiency with respect to the laser.
