Pixelated Laser with Tailored Emission Spectrum Photopatterned by Digital Holographic Microscopy
Advanced Optical Materials, Volume 14, Issue 17, 8 May 2026.Azobenzene‐based surface‐relief gratings inscribed via DHM‐integrated holographic lithography enable programmable pixelated DFB laser architectures. This approach allows independent control of grating parameters across a 2D array, enabling spatially tailored emission spectra.

Optics Express, 2013 We demonstrate photonic devices based on standard 3C SiC epitaxially grown on silicon. We achieve high optical confinement by taking advantage of the high stiffness of SiC and undercutting the underlying silicon substrate. We demonstrate a 20 um radius suspended microring resonator with Q of 18000 fabricated on commercially available SiC-on-silicon ...

Heteronuclear Soliton Molecules in Optical Microresonators [PDF]
Conference on Lasers and Electro-Optics, 2019 AbstractOptical soliton molecules are bound states of solitons that arise from the balance between attractive and repulsive effects. Having been observed in systems ranging from optical fibres to mode-locked lasers, they provide insights into the fundamental interactions between solitons and the underlying dynamics of the nonlinear systems.

Photo‐Reconfigurable Supercoupling Induced Transparency in On‐Chip Topological Edge State Cavities
Advanced Materials, Volume 38, Issue 13, 3 March 2026.A novel supercoupling induced transparency (SIT) is demonstrated in a valley‐Hall photonic crystal. The valley vortices enable the supercoupling between a leaky and a guided topological edge state cavity even across a distance of 4.3 wavelengths, inducing a transparency window with negligible reflection.
