Disclosed is a series of materials, which exhibit large birefringence under the influence of an applied electric field. These materials are capable of switching this large birefringence with a characteristic time on the order of 1 microsecond or less. In addition, these materials have good optical loss at this wavelength, and are stable under irradiation. These materials are suitable for fabrication of optical devices such a variable optical attenuators, switches, and modulators that respond in these time frames or slower. These materials are also suitable for use across a wide range of wavelengths. As a second component of this invention, some of these novel materials exhibit these desired optical properties (large birefringence, low loss, stability under illumination) at wavelengths as short as about 400 nm. These materials are suitable for fabrication of optical devices operating at or about 405 nm, where conventional EO materials strongly absorb and/or quickly degrade.
披露了一系列材料,这些材料在受到外加电场影响下表现出较大的双折射。这些材料能够在大约1微秒或更短的时间内切换这种较大的双折射。此外,这些材料在这个波长下具有良好的光学损耗,并且在辐照下稳定。这些材料适用于制造像可变光学衰减器、开关和调制器等在这些时间范围或更慢响应的光学器件。这些材料也适用于在广泛波长范围内使用。作为本发明的第二个组成部分,一些新型材料在约400纳米的波长下展现出这些理想的光学特性(较大的双折射、低损耗、辐照下的稳定性)。这些材料适用于制造在或约405纳米波长下运行的光学器件,传统的电光材料在这个波长下会强烈吸收和/或迅速降解。
