Reduction of MEMS mirror edge diffraction in a wavelength selective switch using servo-based multi-axes rotationEffects of diffraction of a spectral beam from an edge of the micromirrors are reduced in order to optimize the passband in a wavelength selective switch. The effects of diffraction on ...
with increased complexity and functionalities. We have further experimentally demonstrated diffraction-limited imaging free of aberration and crosstalk at both states of the metalens, proving that active metasurface optics based on O-PCM technologies can indeed attain a high level of optical quality ...
4. The optical dual grating device of claim 3 wherein: the second transparent block is bonded to the first transparent block with index-matching glue; the second transparent block has the same index of refraction as the first transparent block; and the refractive index on both sides of said ...
A 2D diffraction grating light valve modulates an incident beam of light. A plurality of elements each have a reflective surface with their respective reflective surfaces substantially coplanar. Alter
