They trained a five-layer ODNN to construct the light field conversion between the OAM modes and kinetic action (KA) holograms with binary grayscale values. They selected 10 OAM modes (l ∈ [−5, +5], l ≠ 0) a
Despite the thickness of the silver, its high reflectivity makes the MIM grating structure visible. The refractive indices of the surrounding medium, phase grating, separation layer, and MIM dielectric are given by ns, nPG, nZ, and nMIM, respectively. The epoxies SU-8 and mr-EBL have been ...
Referring toFIG. 1, there is shown a multi-wavelength waveguide reflector10in accordance with the invention for operation at a Bragg wavelength of approximately 1.55 μm within the erbium window. The reflector comprises a substrate12of Indium Phosphide (InP); an optical guiding layer14of Indium G...
To optimize the etch rate lectivity, and anisotropy of the device profile, a specific Si3N4 etch recipe was develo for this study. After the reactive-ion etching, a thin layer of residual PR remains on Nanomaterials 2023, 13, 2350 7 of 10 grating, which is eliminated by performing O2 ...
