Total internal reflection light modulating microstructure devices

摘要: A light modulating switch ( 210 ) including a switching element 218 having first portion 226 of electro-optic material to which and second electrodes 213, 224 are associated. 228 is composed an index refraction matching that the when no voltage applied electro-optically activate ), but less than activated by application ). The portions 226, in close conjunction with each other such TIR boundary 230 formed at junction oriented respect least one incident beam 240 enters strikes angle totally reflected internally activated, will pass unreflected through not activated. thickness preferably reduced removal step region 246 so electric field lines within active more narrowly directed flatter regular.
