When nanosecond laser pulses irradiate the surface of a silicon film (a so-called silicon-on-insulator wafer), structural colors can be generated in a tunable fashion. An extended collaboration work, entitled “Structural color due to guided-mode resonance in silicon-on-insulator irradiated by nanosecond”, demonstrates another way in which new functionalities can be obtained by the combination of semiconductor material physics and laser-induced photonic structuring.

“Structural color due to guided-mode resonance in silicon-on-insulator irradiated by nanosecond”
Sci. Technol. Adv. Mater. 27 (1), 2641872 (2026).
The peer-reviewed paper has been published in the journal Science and Technology of Advanced Materials (Taylor & Francis). Another important feature of this paper is that it arises from an international project coordinated by teams at Shizuoka University in Japan and Riga Technical University in Latvia, with collaborations from Vilnius University in Lithuania and the University of Southampton in UK.
We are all looking forward to various directions in which this initial finding can lead and to the new projects that may be developed based on this collaboration network!
