Title: Johan Christer Holm: Innovator in Grating Structures
Introduction
Johan Christer Holm is a notable inventor based in Copenhagen, Denmark. He has made significant contributions to the field of optical engineering, particularly in the development of grating structures. With a total of 2 patents, Holm's work focuses on enhancing diffraction efficiency for various polarizations of light.
Latest Patents
Holm's latest patents include a groundbreaking design for a polarization-independent grating. This innovative grating achieves high diffraction efficiency into the minus first diffracted order in transmission for both TE and TM polarizations. The design allows for the incident angle to be selected so that the minus first diffracted order in reflection can be retroreflected back to the incident beam. The grating can be constructed from multiple materials and layers, with the thicknesses determined through optimization or simulation processes. Notably, the grating may feature a longitudinal refractive index profile with at least two local extrema, such as a maximum or minimum. Additionally, Holm has developed new grating structures that include a bonded transmission grating structure, encapsulated by two bonded pieces. His methods for creating these structures involve forming wells with a significant aspect ratio, enabling high diffraction efficiencies for both TE and TM polarizations of light.
Career Highlights
Holm is currently employed at Ibsen Photonics A/S, where he continues to push the boundaries of optical technology. His work has garnered attention for its innovative approach to grating design and efficiency.
Collaborations
Throughout his career, Holm has collaborated with esteemed colleagues such as Henrik Madsen and Thomas Sorensen. These partnerships have contributed to the advancement of his research and the successful development of his patents.
Conclusion
