Title: Innovations of James R Heflin, Jr.
Introduction
James R Heflin, Jr. is a notable inventor based in Blacksburg, VA (US). He has made significant contributions to the field of non-linear optics and fiber-optic technology. With a total of 4 patents, Heflin's work has advanced the understanding and application of optical materials and sensors.
Latest Patents
One of Heflin's latest patents focuses on the enhancement of second-order non-linear optical susceptibilities in organic film materials using non-centrosymmetric nanoparticles. This innovative non-linear optical material comprises a plurality of non-centrosymmetric nanoparticles juxtaposed to a non-linear optical (NLO) film at a localized surface Plasmon resonance (LSPR) of the nanoparticles. The LSPR is resonant at a wavelength of an incident light source, enhancing the second-order non-linear susceptibility (χ(2)) of the NLO film with respect to the incident light. This non-linear optical material notably lacks global inversion symmetry.
Another significant patent involves a fiber-optic sensor or modulator utilizing the tuning of long period gratings with self-assembled layers. This invention provides an ionic self-assembled multilayer (ISAM) film on a fiber-optic element, including a long period grating (LPG), through a simple, room temperature process. This innovation allows for tuning of the LPG and high sensitivity to the refractive index of the ambient environment. The inclusion of a final layer or a probe, receptor, or affinity ligand in the multi-layer film results in a highly sensitive sensor for specific chemical and biological materials.
