Description

A far-infrared filter is fabricated by creating metallic squares on a dielectric substrate. This capacitive metallic filter is fabricated using direct write laser ablation consisting of a femtosecond laser in combination with a high numerical aperture objective. A representative capacitive filter is fabricated on soda-lime glass substrate with a period of 100 µm and separation width of 30 µm. A capacitive filter was also fabricated on a thin film polypropylene substrate with similar dimensions. The filter was tested and the frequency response is discussed.
