We are delighted to announce that our invited perspective article titled
“Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices”
authored by Sezer Seçkin, Swagato Sarkar, and Tobias A.F. König has been published in Advanced Materials Interfaces.
This work highlights the potential of colloidal metasurfaces—engineered from emitting and plasmonic nanoparticles—to significantly advance nanophotonics applications. By harnessing the combined power of laser interference lithography (LIL) and template-assisted self-assembly (TASA), our team demonstrates how these cutting-edge techniques can direct the self-assembly of nanoparticles with unprecedented precision. The result is an impressive range of enhanced photonic responses, from increased emission intensity and directional enhancement to tunable photonic bandgaps.
What makes these findings particularly exciting for Kingslab is the emphasis on rational nanostructure design to optimize interactions between localized and collective optical modes—paving the way for surface lattice resonances (SLRs) and hybridized guided mode resonances (hGMRs). These phenomena open avenues for high-efficiency light-emitting devices, low-threshold lasing, and highly sensitive surface-enhanced Raman spectroscopy (SERS).
Beyond immediate applications, our perspective discusses how these colloidal metasurfaces can serve as a scalable, low-loss platform for transformative technologies in quantum computing, secure communication networks, and advanced optoelectronic systems. For Kingslab, this publication reinforces our commitment to pushing the boundaries of photonic research and offers a roadmap for future breakthroughs in hybrid fabrication methods.
A special note of gratitude goes to Sezer—this publication marks another key step in his doctoral thesis—and to Swagato, whose contributions have been invaluable. We look forward to further advancing these technologies and sharing more updates as our research progresses.
