Abstract
Metallic nanowire arrays have been used for discriminating linear polarization and used as a wire-grid polarizer in the simplest form. For their linear geometry, metallic nanowire arrays distinguish p- (perpendicular) from s-polarization (parallel) with respect to the direction of nanowire arrays. In this study, we analyze opto-thermal response on metallic nanowire arrays, for which we performed simulation using finite element method to solve wave-coupled heat transfer equations on metallic nanowire arrays. From the analysis, it was shown that s-polarized light presents lower maximum temperature Tmax = 331.7 K than that of p-polarized light Tmax = 354.5 K under an incident power at 0.1 mW/μm2. In addition, thermal extinction which is defined as the ratio of maximum temperature between p- and s-polarization is measured as 4.78 dB which corresponds to a temperature difference of 54.3K. We have also investigated dispersive misregistration assuming that metallic nanowire arrays are integrated with an imaging detector placed at the focal length of a tube lens. The dispersive effect of a convex tube lens was evaluated using non-uniformity metrics that measure offaxis performance (NTroff, ERoff) and wavelength dependence (NTrλ, NERλ). Maximum non-uniformity was measured to be NTrλ.max = 0.84935, NERλ.max = 0.90139, NTroff.max = 0.93211, and NERoff.max = 0.93624. Image misregistration induced by dispersive effects was also assessed.
