Abstract The design, fabrication, and validation of a thin-film lithium niobate on insulator (LNOI) electro-optic (EO) time-domain terahertz (THz) wave detector is reported. LNOI offers unprecedented properties for the EO detection of freely propagat

Thin film lithium niobate based electric field sensing is demonstrated using both micro-ring and Mach-Zehnder modulators. A high sensitivity of 80 mV/(m.Hz1/2) and of 2.2 V/(m.Hz1/2) is achieved using micro-ring modulators and Mach-Zehnder modulators

In this paper, a scheme is developed for measuring electron bunch lengths in Free Electron Lasers (FELs) and Linear Accelerators (LINACs). The presented scheme uses integrated thin-film lithium niobate (LiNbO 3 or LN) Mach-Zehnder interferometers (MZ

Thin film lithium niobate optical modulators allow modulation of optical signals up to several THz due to perfect phase matching between RF signal and optical signal that can be achieved using thin film devices. The platform uses a ridge waveguide fa

We present our results for using thin film lithium niobate devices for electric field sensing applications. Micro-ring modulator and Mach–Zehnder modulator-based electric field sensors are demonstrated. Micro-ring resonator sensors can be used for

We propose a non-invasive, large-bandwidth electro-optic (EO) detection scheme for high-frequency electric fields using thin-film lithium niobate Mach–Zehnder interferometers. Our proof-of-concept device is capable of detecting high-strength electr

The frequency response of microring modulators is analyzed using the Jacobi-Anger expansion method. The linearity of coupling-modulated microring (CMMR) modulators is analyzed. It is shown that the CMMR modulators can achieve a spurious-free dynamic
