SPATIAL LIGHT MODULATORS, METHODS OF DRIVING AND MANUFACTURING THE SAME, AND APPARATUSES INCLUDING THE SPATIAL LIGHT MODULATORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17987282 titled 'SPATIAL LIGHT MODULATORS, METHODS OF DRIVING AND MANUFACTURING THE SAME, AND APPARATUSES INCLUDING THE SPATIAL LIGHT MODULATORS
Simplified Explanation
The patent application describes spatial light modulators and methods of driving and manufacturing them. The spatial light modulator includes a substrate, a distributed Bragg reflector (DBR) layer, a cavity layer, a pixel layer, and a heat blocking member.
- The spatial light modulator includes a substrate, a DBR layer, a cavity layer, a pixel layer, and a heat blocking member.
- The DBR layer is stacked on one surface of the substrate.
- The pixel layer includes a plurality of pixels, and each pixel includes a plurality of active meta-patterns.
- A material layer with lower thermal conductivity than the lowermost layer of the DBR layer is provided between the substrate and the DBR layer.
- The material layer, DBR layer, and cavity layer are divided corresponding to the plurality of pixels.
- The heat blocking member is provided between the divided material layers, divided DBR layers, and divided cavity layers.
Potential applications of this technology:
- Display devices
- Optical communication systems
- Holographic imaging systems
- Optical data storage systems
Problems solved by this technology:
- Heat transfer between pixels is blocked, preventing interference and degradation of image quality.
- The material layer with lower thermal conductivity helps to dissipate heat more efficiently.
- The divided layers allow for individual control and manipulation of each pixel.
Benefits of this technology:
- Improved image quality and resolution
- Enhanced heat dissipation and thermal management
- Increased control and flexibility in pixel manipulation
- Higher efficiency and reliability in spatial light modulation.
Original Abstract Submitted
Provided are spatial light modulators, methods of driving and manufacturing the same, and apparatuses including the spatial light modulators. The spatial light modulator according to an example embodiment includes a substrate, a distributed Bragg reflector (DBR) layer stacked on one surface of the substrate, a cavity layer on the DBR layer, a pixel layer on the cavity layer and including a plurality of pixels, and a heat blocking member between the plurality of pixels to block heat transfer between the plurality of pixels, wherein a material layer having a lower thermal conductivity than the lowermost layer of the DBR layer is provided between the substrate and the DBR layer, and each of the plurality of pixels includes a plurality of active meta-patterns. In one example, the material layer, the DBR layer, and the cavity layer are each divided corresponding to the plurality of pixels, and the heat blocking member is provided between the divided material layers, between the divided DBR layers, and between the divided cavity layers.
