<p>A linearly polarized light converter uses a polarization recycling mechanism for separating a first linearly polarized wave (201) of an unpolarized wave (20) that includes orthogonal first and second linearly polarized waves (201, 202) and that is produced by a light source (2) . The linearly polarized light converter includes a polarized beam splitter (3) disposed on a first side (21) of the light source (2) for receiving the unpolarized wave (20), transmitting the first linearly polarized wave (201) therethrough, and reflecting the second linearly polarized wave (202). A metallic reflector (4) is disposed on a second side (22) of the light source (2) that is opposite to the first side (21), and includes a metal layer (42) and a plurality of metal particles (43) distributed over the metal layer (42) to cooperatively define a rough surface (40) which converts the reflected second linearly polarized wave (202) into an elliptical polarized wave (20') and which reflects the elliptical polarized wave (20') therefrom.</p> |
