Bounded frequency lattices in integrated lithium niobate coupled ring cavities

Hiep X. Dinh, Armandas Balčytis, 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…

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…
