Researchers Simulate Novel Metal-Filtered VCSEL Mode Control

Structure of MMF-VCSEL. Credit: Sensors (2024). DOI: 10.3390/s24144700 A study led by researchers from the Changchun Institute of Optics, Precision Mechanics and Physics, Chinese Academy of Sciences, has revealed a new metal-dielectric film mode filter structure that allows for flexible control of the transverse modes of vertical-cavity surface-emitting lasers (VCSELs), demonstrating the potential of metal apertures for enhanced mode control…
