Use the hole punch to make a hole in the center of one of the stickers. Position the diffraction grating on the adhesive side of the sticker so it covers the hole you just made, then press it into ...

Music is digitally recorded as circular tracks of ones and zeros on the mirrored surface of a CD. These circular tracks are so close together that they can act as a diffraction grating for light. When ...

Abstract: We present experimental results on surface relief gratings in GaAs and InP with high reflectivity (>85%) and polarization selectivity to normal incidence from the semiconductor side. The ...
