#This application claims all benefits accruing under 35 U.S.C. §119 from China Patent Application No. 201310042255.X, filed on Feb. 4, 2013 in the China Intellectual Property Office. This application is also related to the applications entitled, “PHOTORESISTOR”, filed Apr. 8, 2013 Ser. No. 13/858,722 and entitled “POLARIZED LIGHT DETECTION SYSTEM”, filed Apr. 8, 2013 Ser. No. 13/858,735. Disclosures of the above-identified applications are incorporated herein by reference.

#1. Technical Field

#The present disclosure relates to methods for detecting polarized light.

#Many aspects of the present disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments.

#FIG. 1 is a schematic diagram of a photoresistor according to one embodiment.

#FIG. 2 is an exploded view of a carbon nanotube film structure used in the photoresistor of FIG. 1.

#The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “another,” “an,” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

#Referring to FIG. 1, a photoresistor 10 of one embodiment includes a first electrode layer 102, a photosensitive material layer 104, and a second electrode layer 106. The first electrode layer 102, photosensitive material layer 104 and second electrode layer 106 are stacked with each other. The photosensitive material layer 104 has a first surface 1042, a second surface 1044 opposite to the first surface 1042, and at least one side surface connecting the first surface 1042 to the second surface 1044. The first electrode layer 102 is attached to the first surface 1042 of the photosensitive material layer 104; and the second electrode layer 106 is attached to the second surface 1044 of the photosensitive material layer 104. The first electrode layer 102 and second electrode layer 106 are electrically contacted to the photosensitive material layer 104.

#In one embodiment, the first electrode layer 102 and second electrode layer 106 cover the entire first surface 1042 and the entire second surface 1044, respectively. In another embodiment, the first electrode layer 102 and second electrode layer 106 cover parts of the first surface 1042 and parts of the second surface 1044, respectively.
