Paper Abstract

Enhanced optical transmission of metallic nanohole arrays stimulated the blooming research efforts on plasmonics and rich applications. Here we studied the dependence of enhanced optical absorption on geometric parameters by nanohole arrays on gold films in infrared wavelength (8~12μm). An empirical modeling for enhanced optical absorption is summarized (based on a great many of simulation data and deviation analysis, and its goodness-of-fit test and significance test is acceptable), which takes consideration of not only single parameters but also interaction parameters of geometries. Through t-test, the interaction parameters with high significance are chosen, which could give high optical absorption, and the interaction of different parameters was evaluated via Analysis of Variance (ANOVA). Our study represents a new guiding rule for uncooled infrared detector design.
