    • The invention is directed to polarizing devices that can be scaled to polarize electromagnetic radiation having wavelengths in ultraviolet to microwave range; and more particularly to devices suitable for use at visible and IR wavelengths. The device has a length, a width and a thickness, and a patterned system of channels, voids or holes embedded in or through a glass matrix and running through the thickness of the glass to thereby polarize incoming electromagnetic radiation having two polarization modes orthogonal to one another, blocking the passage of or reflecting one mode and permitting the other mode to pass through the device. The glass can be any glass suitable for transmitting the electromagnetic radiation in the range it will be used without excessive transmission losses due to absorbance of radiation in that range by moieties present in the glass. In one aspect, the device according to the invention may be deemed a "universal" polarizer: in the sense that it can be made to work in wavelength ranges from the microwave to the ultraviolet. The devices can also be made of polymeric materials utilizing the principles enumerated in the specification.
    • 本发明涉及可以缩放以使具有紫外至波长范围的波长的电磁辐射极化的偏振装置; 并且更具体地涉及适用于可见光和IR波长的装置。 该装置具有长度,宽度和厚度,以及嵌入或穿过玻璃基体并且穿过玻璃的厚度的通道,空隙或孔的图案化系统,从而极化具有与一个正交的两个偏振模的入射电磁辐射 另一个,阻止或反射一种模式,并允许其他模式通过设备。 玻璃可以是任何玻璃,适用于在不影响透射损失的范围内传输电磁辐射,这是由于玻璃中存在的部分的辐射吸光度。 在一个方面,根据本发明的装置可以被认为是“通用”偏振器:在可以使其在从微波到紫外线的波长范围内工作的意义上。 这些装置也可以由使用说明书中列举的原理的聚合材料制成。
