Paper Abstract

Optical material characterization encompasses absorption, refraction and scattering phenomena as a function of frequency and temperature. The level of knowledge of the optical constants for most optical materials is sparse, especially at temperatures outside of room temperature. Critical future applications will require a more complete database. The need for greater precision in the optical constants requires both improved experimental techniques and more detailed modes. Since a comprehensive experimental database is impossible, physically-based models, allowing accurate interpolation and extrapolation, are an essential part of optical characterization. Furthermore, most optical constant characterization is reported in the frequency- domain. However, high-speed optoelectronic materials require time-domain characterization.
