Problems solved by technology

However, the nonlinear effect of inorganic materials mainly originates from the lattice distortion and resonance absorption of the material, and the response time is often relatively long, which is far from meeting the development requirements of modern optical communication technology.
In addition, inorganic materials have disadvantages such as cumbersome preparation process, few types to choose from, and easy deliquescence, which greatly limit their research progress and practical application.

Description

[0001] technical field [0002] The invention belongs to the field of functional materials, and in particular relates to a synthesis method of 4-(4-dimethylaminostyryl)picoline trifluorosulfonate and an application as an organic third-order nonlinear optical material. Background technique [0003] Optical fiber communication technology is an important way to meet the requirements of ultra-large capacity information collection, processing, transmission, storage and display. However, there are a large number of electronic devices used for signal switching and processing in existing optical fiber communication systems. Due to the disadvantages of clock skew, serious crosstalk, high loss, and slow response, these devices have become the "limitation point" that limits the improvement of information carrying capacity. bottleneck". Using third-order nonlinear optical materials to prepare optical components such as all-optical switches, optical computing, optical cross-connectors, ...
