Introduction

Christopher Hwang is a prominent inventor based in Watertown, MA (US). He has made significant contributions to the field of laser technology, holding 2 patents that address critical challenges in the coherent combining of laser beams.

Latest Patents

Hwang's latest patents include innovative methods for incoherently combining lasers and a fabrication method for endcapped fiber laser pigtails with sub-micron virtual waist positional accuracy. The first patent focuses on the challenge of combining light from different lasers while maintaining high brightness. By tapering the tips of bundled fibers to match a single, multi-mode output fiber, Hwang's method increases the brightness of the beam combining. Additionally, reducing the outer diameters of the signal fiber claddings allows for closer bundling of signal fibers, enhancing the coupling of more signal fiber cores to the output fiber.

The second patent addresses the alignment issues in fiber pigtail arrays used for projecting and receiving light. Hwang's method improves the precision of aligning optical fibers to their endcaps, which is crucial for coherent beam combining. By measuring the virtual beam waist position before and after splicing the endcap, he reduces deviations among endcapped fibers, facilitating the production of precisely aligned arrays.
