Integrated photonics provides an important platform for simulating physical models with high-performance chip-scale devices, where the lattice size and time dependence of a model are key ingredients further enriching functionality photonic chip. Here, we propose demonstrate construction various time-varying Hamiltonian using single microresonator on thin-film lithium niobate Such integrated holds high-quality factor to 10^{6}, supports synthetic frequency effective sites up 221 under...
The erbium-doped lithium niobate on insulator (Er:LNOI) has garnered significant attention as it combines outstanding gain property with integration capabilities, making a promising solution for active devices the versatile LNOI platform. This also paves way development of appealing waveguide amplifiers. Here, we demonstrate an efficient integrated Er:LNOI micro-waveguide amplifier directly compatible lens fiber. In 5.6-cm-long micro-waveguide, maximum internal net 18.8 dB 1531-nm signal...
Polarization controlling devices on thin-film lithium niobate (TFLN) are critical components for photonic integrated circuits (PICs) the platform because birefringence of intrinsically determines its polarization-dependent property. Here, we propose and demonstrate a compact polarization splitter-rotator (PSR) TFLN based two adiabatic tapers an asymmetric directional coupler with effective length only 240 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML"...

High-speed photonic integrated circuits leveraging the thin-film lithium niobate (TFLN) platform present a promising approach to address burgeoning global data traffic demands. As pivotal component, TFLN-based electro-optic (EO) Mach-Zehnder modulators (MZMs) should exhibit low driving voltage, broad operation bandwidth, high extinction ration, and insertion loss. However, pursuit of both maximal EO overlap integral minimal microwave loss necessitates fundamental compromise between voltage...
