摘要：
Metal included semiconductor ultrathin films for laminated polarizers are proposed. Compound films consisting of germanium and stainless steel are fabricated by use of a rf magnetron sputtering system. Generally speaking, imaginary parts of the specific dielectric constants of the films increase in proportion to the metal concentration. Laminated polarizers utilizing the compound films as absorptive layers are found to have high performances, extinction ratios more than 50 dB with insertion losses less than 0.2 dB over the wavelength range from visible to infrared.
