Abstract: The present invention comprises: (a) a polarizer element (12); and (b) an array of tapered waveguides (10) in substantial contact with the polarizer element (12) wherein: (i) the tapered end of each of the waveguides extends outward from the polarizer element (12), (ii) each of the waveguides (10) has a light input surface adjacent the polarizer element (12) and a light output surface distal from the light input surface, (iii) the area of the light input surface of each of the waveguides (10) is greater than the area of its light output surface, and (iv) the waveguides (10) in the array are separated by interstitial regions (14) with a lower refractive index than the refractive index of the waveguides (10). The present improved polarizer may be used in display devices, such as for example projection display devices, off screen display devices, and direct view displays. Such displays are used in a wide range of applications including computer terminals, airplane cockpit displays, automotive instrument panels, televisions, and other devices that provide text, graphics, or video information.
