Abstract
Recent simulation and experimental work has resulted in the realization of low-cost, substrate-based, THz wire-grid polarizers fabricated on crystalline-quartz substrates that exhibit both high extinction ratios and low insertion losses. The broad bandwidth performance of these high fill-factor wire-grid polarizers are characterized using terahertz time-domain spectroscopic techniques over a frequency range spanning from 0.25 to 2 THz. The polarizers exhibited extinction ratios as high as 50 dB at low frequencies and 30 dB at higher ones.
