Title: The Innovations of John F. Klem
Introduction
John F. Klem, a prominent inventor based in Albuquerque, NM, has made remarkable contributions to the field of optical devices and semiconductor technology. With 12 patents to his name, Klem’s innovative work continues to push the boundaries of scientific discovery and application.
Latest Patents
Among his latest patents, Klem has developed an efficient ultrathin all-dielectric nonlinear optical device. This apparatus and method generate harmonic light from a pump beam that strikes a metasurface featuring multiple all-dielectric resonator bodies. Intriguingly, the structure includes a multiple quantum well framework in each resonator, incorporating asymmetric coupled quantum wells that align with Mie resonances of the resonator bodies.
Another noteworthy invention is his superlattice photodetector, which boasts improved carrier mobility. In this design, each superlattice period consists of first and second semiconductor layers with different compositions. Notably, at least one layer comprises indium arsenide (InAs), with a graded composition in one of the layers—specifically, an indium arsenide antimonide (InAsSb) layer whose antimony concentration varies. This innovative composition gradually increases from both ends toward the center of the layer, enhancing the device's performance.
