Van der Waals heterostructure mid-infrared emitters with electrically controllable polarization states and spectral characteristics
Po-Liang Chen, Tian-Yun Chang, Pei-Sin Chen +11
Modern infrared (IR) microscopy, communication, and sensing systems demand control of the spectral characteristics and polarization states of light. Typically, these systems requir…
Ultrathin van der Waals metalenses
Chang-Hua Liu, Jiajiu Zheng, Shane Colburn +4
Ultrathin and flat optical lenses are essential for modern optical imaging, spectroscopy, and energy harvesting. Dielectric metasurfaces comprising nanoscale quasi-periodic resonat…
Silicon photonic crystal cavity enhanced second-harmonic generation from monolayer WSe2
Taylor K. Fryett, Kyle L. Seyler, Jiajiu Zheng +3
Nano-resonator integrated with two-dimensional materials (e.g. transition metal dichalcogenides) have recently emerged as a promising nano-optoelectronic platform. Here we demonstr…
