A judicious selection of polymer materials for the fabrication of a deformable-membrane light modulator (e.g., the photoemitter membrane light modulator) will enhance its speed. A polymer with a low surface energy decreases the device response time by lowering the membrane tension that is caused by the surface interaction between the membrane and an adjacent dielectric surface. The material must also have high temperature stability. A composite structure of parylene on poly[bis(trifluoroethoxy)phosphazene] on SiO(x) is found to meet these requirements, with stability to 220 degrees C and a tension of 0.18 N/m, giving a potential frame rate of close to 10 kHz or a throughput of10(10) pixels/sec. |
