Abstract
In this paper, a
complete investigation and
simulation of the extinction ratio (ER) in a setup with a
micro-polarizer array (MPA) is performed. A metal grid substrate
structure, which can effectively reduce optical crosstalk and improve
the ER, is proposed. The numerical calculation results show that the
ER of our proposed structure is more than 10-fold higher than that of
the traditional structure. Moreover, the effect of its structural
parameters to the ER has been researched, and the results showed that
when the substrate is thicker, the incident angle of light is less
than 15°, the metal width is larger than 900 nm, and a complete
grating with more than 20 periods on a single pixel can obtain a high
ER.
