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…
Black phosphorus van der Waals heterostructures light emitting diodes for mid-infrared silicon photonics
Tian-Yun Chang, Yueyang Chen, De-In Luo +9
Light-emitting diodes (LEDs) based on III-V/II-VI materials have delivered a compelling performance in the mid-infrared (mid-IR) region, which enabled wide-ranging applications, in…
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…
Flexible and Transparent All-Graphene Circuits for Quaternary Digital Modulations
Seunghyun Lee, Kyunghoon Lee, Chang-Hua Liu +2
In modern communication system, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a…
Evidence for Extraction of Photoexcited Hot Carriers from Graphene
Chang-Hua Liu, Nanditha M. Dissanayake, Seunghyun Lee +2
We report evidence of nonequilibrium hot carriers extraction from graphene by gate-dependent photocurrent study. Scanning photocurrent excited by femtosecond pulse laser shows unus…
