Fabrication and characterisation of a 4*4 array of polymer-based asymmetric Fabry-Perot reflection modulators

摘要

The fabrication and optical characterisation of a 4*4 array of asymmetric Fabry-Perot (AFP) electro-optic modulators is reported. The electro-optic material used, a cross-linked polymer based on an azo-benzene derivative, offers the potential for high time-bandwidth modulation. The uniformity of the spatial light modulator is evaluated, and a contrast ratio exceeding 4:1 can be obtained simultaneously at each of the 16 pixel positions.
