Optical Filters Based On Nano-Sized Hole And Slit Patterns In Aluminum Films
IEICE TRANSACTIONS ON ELECTRONICS(2016)
摘要
The optical properties of arrays of nanoholes and nanoslits in Al films were investigated both numerically and experimentally. The choice of Al was based on its low cost and ease of processing, in addition to the fact that it has a higher plasma frequency than gold or silver, leading to lower optical losses at wavelengths of 400 to 500 nm.
