We demonstrate a transparent-conductive-oxide combined thin-film lithium niobate modulator with an ultra-high modulation efficiency of 1.02 V cm. The modulator exhibits an EO 3 dB transmission roll …

In this work, we demonstrate a monolithic integrated LN modulator with an ultra-high spurious-free dynamic range (SFDR) of 120.04 dB·Hz4/5 at 1 GHz, using a ring-assisted Mach–Zehnder …

Our modulator provides an order of magnitude lower power consumption with ultra-high Q, low loss, and ER, V π L α and a tuning sensitivity consistent with control applications.

By strongly confining the optical and mechanical waves, this modulator improves a figure-of-merit that accounts for both acousto-optic and electro-mechanical efficiency by orders of magnitude.

We demonstrate silicon Mach-Zehnder Interferometer (MZI) optical modulator with 50.1-Gb/s data rate and 5.56 dB dynamic extinction ratios. The phase shifter is composed by a 4 mm-long reverse …

The modulator is capable of incorporating pre-emphasis function in the optical domain, and hence no longer needs an electrical pre-emphasis driver. By biasing it at a different initial phase difference, the …

Jul 27, 2023 · The optical and radio frequency parameters of the modulator are systematically simulated, calculated, and optimized, respectively.

Apr 28, 2025 · In this work, we present a large-bandwidth TFLN modulator with a low fiber-to-fiber loss, employing grating couplers with metal mirrors for perfectly vertical coupling, which facilitates wafer …

We describe novel techniques for closed-loop control of inner and outer Mach–Zehnder (MZ) biases in a dual parallel MZ (DPMZ) optical modulator. We also present a new technique based on modulator …

Nov 14, 2024 · We demonstrated a high-order mode modulator based on thin-film lithium niobate (TFLN). By introducing a mode converter and a polarization splitter-rotator (PSR), the modulator can …
