ADVANCED OPTICAL MATERIALS AND STRUCTURES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240295763 titled 'ADVANCED OPTICAL MATERIALS AND STRUCTURES

The device described in the patent application includes a pair of electrodes and a dynamic material with a crystalline microstructure that can change between different states in response to an electric field.

• The dynamic material in the device contains tetragonal lead magnesium niobate-lead titanate (PMN-PT) and at least one lanthanide series element.
• The method outlined in the patent involves doping the PMN-PT material with lanthanide series elements and processing it to form tetragonal PMN-PT.
• Another method described in the patent involves creating a nanostructured grating with low refractive index, a high refractive index layer, and an adhesive layer to affix the nanostructured coupling element to a high index waveguide.

Potential Applications: - This technology could be used in actuators, sensors, and other devices that require materials with tunable properties. - It could also have applications in telecommunications, optics, and photonics industries.

Problems Solved: - The technology addresses the need for materials that can change states in response to electric fields. - It provides a method for creating nanostructured elements for improved optical performance.

Benefits: - Enhanced performance in devices that require materials with tunable properties. - Improved optical coupling and transmission efficiency in waveguides.

Commercial Applications: Nanostructured materials like the ones described in the patent could have significant commercial applications in telecommunications, photonics, and optical industries.

Questions about the technology: 1. How does the addition of lanthanide series elements impact the properties of the PMN-PT material? 2. What are the potential challenges in scaling up the production of nanostructured coupling elements for commercial use?

Original Abstract Submitted

a device includes a pair of electrodes and a dynamic material disposed between the pair of electrodes, the dynamic material including a crystalline microstructure configured to change between at least two states in response to a change in an electric field between the two electrodes. a material includes tetragonal lead magnesium niobate-lead titanate (pmn-pt) and at least one lanthanide series element. a method includes doping a lead magnesium niobate-lead titanate material with at least one lanthanide series element, and processing the pmn-pt material to form tetragonal pmn-pt. a further method includes forming a low refractive index nanostructured grating over a carrier substrate, forming a high refractive index layer over the low refractive index grating to produce a nanostructured coupling element, forming an adhesive layer over the nanostructured coupling element, and affixing the nanostructured coupling element to a high index waveguide.
