Title: Karl Peter Welna: Optical Resonator and Waveguide Innovation.

Introduction

Karl Peter Welna is an inventor associated with Fife, United Kingdom, and the University Court of the University of St. Andrews. His recorded patent work concerns an optical system designed to couple light between a waveguide and a resonator.

Latest Patents

Welna is associated with 1 patent: “Wave vector matched resonator and bus waveguide system.” The invention describes an optical device with a waveguide that carries at least one optical mode and wavelength, alongside one or more resonators with resonant wavelengths. The resonator has a mode volume of less than ten cubic resonant wavelengths. In operation, light couples vertically from the waveguide into a resonator, with the components arranged to achieve wave-vector matching between their modes.

Career Highlights

The patent reflects work in optical-device design, particularly the integration of waveguides and compact resonators. The available information associates Welna’s work with the University Court of the University of St. Andrews.

Collaborations

Welna’s listed coworkers include William Whelan-Curtin and Thomas Fraser Krauss.

Conclusion

Karl Peter Welna’s recorded patent contribution focuses on wave-vector matching in a waveguide-and-resonator system, an approach intended to support efficient optical coupling.
