Abstract
In this paper, we present the simulation and preparation in IP-Dip material of a polymer grating, which is used as a highly reflective and spectrally selective mirror based on monolithic high-contrast grating (MHCG) geometry. We simulated the power reflectance as a function of the grating parameters and prepared the grating structure in IP-Dip material using three-dimensional laser lithography. The 3D morphology of the prepared devices was analyzed using a scanning electron microscope. Finally, their spectral power reflectance characteristics were measured and compared with the simulations. The prepared and simulated MHCG structures exceeded 70% power reflectance in the narrow spectral region of 740–810 nm.
