Value Proposition:
· Enhanced tunability and spatial patterning ability for both polar and azimuthal orientations
· Efficient and less error-prone liquid crystal patterning processes
· Versatility in pretilt angles for a variety of applications
· Stable liquid crystal configurations that reduce the need for external voltages and other active controls
Unmet Need
Current methods for liquid crystal applications lack the ability to precisely and continuously pattern both in-plane and out-of-plane orientations at sub-micrometer resolution without complex fabrication steps. Existing approaches often require stacked alignment layers, patterned electrodes, or physically tilting the sample, making them cumbersome, expensive, and limited in scalability. These techniques require multi-step processes, specialized equipment, or external electric fields to maintain desired LC alignment. Therefore, there is critical need for a simple, scalable, and mask-free technique that enables high-resolution, continuous 3D alignment of liquid crystals while maintaining stability without external fields. Such a method would open new possibilities in designing novel liquid crystal-based flat optical elements and adaptive photonics, which can drive innovation in the AR/VR and biomedical imaging spaces.
Technology Description
Researchers at Johns Hopkins have developed a two-step photo-exposure method that allows for simultaneous control of polar and azimuthal orientations of the LC director. The combination of polarized and unpolarized light allows for control over a wide range of orientations and for creating spatially patterned orientations with micrometer-sized features.
Stage of Development
· Technology prototype developed and validated in a controlled laboratory setting.
· Looking for partners to scale up technology for mass production and determine the long-term stability and durability of devices utilizing technology.
