What changed

This document is a published patent application from the USPTO for Lightwave Logic, Inc., titled 'Chromophores with New Bridges that Increase Refractive Index'. The application (US20260085236A1) describes novel nonlinear optical (NLO) chromophores that exhibit enhanced refractive index, photostability, and thermal stability, alongside fast modulation speeds and large electro-optic effects. These advancements are particularly suited for electro-optic modulators (EOMs) in low-power and compact devices used in data acquisition, instrumentation, and power supply applications.

As this is a patent application, it does not impose immediate compliance obligations. However, it signals potential future technological developments and intellectual property in the field of electro-optic materials. Companies operating in related sectors, such as advanced materials, telecommunications, and electronics manufacturing, should monitor patent filings and issued patents to understand emerging technologies and potential licensing or competitive landscapes.

Abstract

The present disclosure is directed, in general, to (1) nonlinear optical (NLO) chromophores, including (2) compositions/materials/resistive layers comprising NLO chromophores, and the methods of making the compositions/materials/resistive layers comprising NLO chromophores (e.g., methods of poling and/or drying, and the like), (3) uses of NLO chromophores in electro-optic devices (e.g., electro-optic modulators (EOMs)). NLO chromophores disclosed herein not only have large EO effect, but also have fast modulation speed. In addition, NLO chromophores disclosed herein have superior refractive index, photostability and thermal stability compared to other EO Materials. As a consequence, NLO chromophores herein are particularly suited for use as EO materials in connection with low power and small footprint devices, including devices used in data acquisition systems, analog I/O modules, field transmitters, lab and field instrumentation, servo drive control modules, direct current (DC) power supply, alternating current (AC), and/or electronic load.
