Bounded frequency lattices in integrated lithium niobate coupled ring cavities
Hiep X. Dinh, Armandas BalÄytis, Guanghui Ren +3
Synthetic dimensions provide a powerful tool that uses comparatively simple structures to probe high-dimensional topological physics, in which edge states emerging at lattice bound…
High efficiency and compact lithium niobate non-resonant recirculating phase modulator and its applications
Feiyu Wang, Liheng Wang, Mingrui Yuan +12
High modulation efficiency and a compact footprint are critical for next-generation electro-optic (EO) modulators. We introduce a new class of non-resonant recirculating phase modu…
Single Vanadium Dioxide Nanoparticle-Enabled Plasmonic switch with Thermal and Electronic Reconfigurability
Gregory Tanyi, Daniel Peace, Han-Hao Cheng +7
We present an integrated switch that combines plasmonic and neuromorphic technologies with a single sub-stoichiometric VO2-x nanoparticle. The presented device acts as a versatile…
Suspended Z-cut lithium niobate waveguides for stimulated Brillouin scattering
Lisa-Sophie Haerteis, Yan Gao, Aditya Dubey +8
On-chip stimulated Brillouin scattering (SBS) has recently been demonstrated in thin-film lithium niobate (TFLN), an emerging material platform for integrated photonics offering la…
On-chip GaAs carrier lifetime investigation
Chawaphon Prayoonyong, Crispin Szydzik, Guanghui Ren +5
We propose an alternative way to determine GaAs carrier lifetime using pump-probe measurement based on fibre optics and integrated waveguides. We find that our GaAs samples have th…
One Million Quality Factor Integrated Ring Resonators in the Mid-Infrared
Marko Perestjuk, Rémi Armand, Miguel Gerardo Sandoval Campos +10
We report ring resonators on a silicon germanium on silicon platform operating in the mid-infrared wavelength range around 3.5 - 4.6 μm with quality factors reaching up to one mil…
