Introduction

Eric Warren Stiers is a notable inventor based in Madison, Wisconsin. He holds three patents that showcase his contributions to the field of semiconductor technology. His work has significantly advanced the understanding and application of laser diodes.

Latest Patents

One of his latest patents is for a semiconductor laser diode. This invention comprises a p-n junction that includes a substrate, an n-type semiconductor layer, a p-type semiconductor layer, and a quantum well. The quantum well is strategically placed between the n-type and p-type layers. The substrate is made from a first material system, while the n-type and p-type layers are formed from different material systems. This design enhances the recombination rate of electrons and holes in the quantum well, resulting in a lower turn-on voltage for the laser diode. Another significant patent is for a narrow lateral waveguide laser. This edge-emitting semiconductor laser features a narrow waveguide design that expands the lateral mode size and ensures that higher-order modes are beyond cutoff. The separate current confinement allows the current injection region to align with the mode size, leading to single-mode operation with a large spot size and high output powers.
