Abstract :
We describe a new method of polarization sensing using a resonant cavity enhanced (RCE) photodetector vertically integrated with a conventional detector. Establishing polarization selectivity in a compact semiconductor device structure is strongly desirable for many applications, ranging from imaging arrays to magneto-optic data storage. In imaging, there is a compelling motivation to study polarization vision. Beside the color and intensity of light, polarization may underlie additional information in an image.
