Abstract
The optical absorption of thin-film thermal infrared detectors was calculat ed as a function of wavelength, pixel size, and area fill factor by use of the finite-difference time-domain (FDTD) method. The results indicate that smaller pixels absorb a significantly higher percentage of incident energy than larger pixels with the same fill factor. A polynomial approximation to the FDTD results was derived for use in system models. (C) 2001 Optical So ciety of America.
