LIGHT MODULATOR, OPTICAL DEVICE INCLUDING LIGHT MODULATOR, AND ELECTRONIC APPARATUS INCLUDING OPTICAL DEVICE: abstract simplified (18334838)

• This abstract for appeared for patent application number 18334838 Titled 'LIGHT MODULATOR, OPTICAL DEVICE INCLUDING LIGHT MODULATOR, AND ELECTRONIC APPARATUS INCLUDING OPTICAL DEVICE'

Simplified Explanation

The abstract describes a light modulator that can change the phase of incident light by adjusting its refractive index. The modulator consists of a substrate and a resonator. The resonator includes a first reflective structure on the substrate, a cavity layer on top of the first reflective structure, and a second reflective structure on the cavity layer. The first and second reflective structures are made up of alternating layers of different materials, while the cavity layer is made of a third material. Each material layer has a different refractive index.

Original Abstract Submitted

Provided is a light modulator including a substrate, and a resonator configured to modulate a phase of incident light by modulating a refractive index based on an external stimulus, the resonator comprising a first reflective structure provided on the substrate, a cavity layer provided on the first reflective structure, and a second reflective structure provided on the cavity layer, wherein at least one of the first reflective structure or the second reflective structure comprises first material layers, second material layers that are alternately stacked with the first material layers, and a third material layer, and wherein each of the first material layers has a first refractive index, each of the second material layers has a second refractive index that is different from the first refractive index, and the third material layer has a third refractive index that is different from the first refractive index
