Joel Yang

Joel Yang serves as the Otto Mønsted Visiting Professor at POLIMA, University of Southern Denmark (SDU), for the 2024-25 academic year, visiting from Singapore University of Technology and Design (SUTD). His appointment as a Visiting Professor confirms active faculty status within SDU's research ecosystem.

Yang's research centers on nanophotonics and advanced nanofabrication, with specialization in 3D printing techniques for photonic crystals and metasurfaces. His work bridges fundamental optical physics with applications in structural color generation, infrared photodetection, and quantum emitter systems. Key methodologies include two-photon polymerization lithography and phase change material engineering, targeting visible-to-mid-IR spectral ranges.

Analysis of his 2024-2025 publications reveals concentrated innovation in visible-spectrum photonic crystals (e.g., glass/titania 3D printing with complete bandgaps) and ultra-wideband metasurface detectors. Recurring themes include electrical tunability of quantum emitters, interband plasmonics for UV applications, and amorphization-dependent recrystallization processes in phase change materials. This trajectory demonstrates systematic scaling of nanofabrication techniques toward practical optical devices.
