By depositing a resolution test pattern on top of a Si3N4 photonic crystal resonant surface. we have measured the dependence of spatial resolution on refractive index contrast Δn. Our experimental results and finite-difference time-domain (FDTD) simulations at different refractive index contrasts show that the spatial resolution of our device reduces with reduced contrast. whic... https://www.freeebookfinder.com/product-category/fr-pants/
