We propose an optica1-terahertz link using a triply-resonant photonic molecule and discuss its applications for terahertz signal detection and synthesis using traditional RF and optical techniques. Our design is a low-cost alternative to THz frequency generation via microwave drives and can be operated in both continuous-wave and pulsed regimes.

This work presents a superconducting microwave resonator that is both frequency tunable and compatible with photolithography. This design is well-suited for integration with electro-optic devices. We demonstrate tuning ranges exceeding 500 MHz, using a bulk permanent magnet, and 100 MHz, using planar coils, under moderate magnetic fields (below 5 mT).

This work presents a dual-tone source on thin film lithium niobate for generating a tunable carrier frequency at the terahertz domain. The system exhibits stable carrier generation above 100 GHz with sub-kHz linewidth and tunability of over 5 GHz.

Terahertz technologies offer unique advantages for communication, sensing, and imaging, yet integrated platforms struggle to perform efficiently in this range. Thin-film lithium niobate, a nonlinear photonic platform, enables compact, broadband, and high-speed terahertz sources through efficient frequency conversion. In this talk, I present our progress on developing subterahertz continuous-wave sources on lithium niobate chips, aiming to bridge the gap between electronic and photonic systems for next-generation terahertz integration.

We present frequency-tunable, photolithography compatible superconducting microwave resonators designed for integration with electro-optic devices. We demonstrate >500 MHz of tuning with a bulk permanent magnet and > 1 00 MHz of tuning with planar coils under moderate (<5 mT) magnetic fields.

We present a photonic integration method combining flip-chip bonding and photonic wirebonding. This approach enables a 'mother' substrate to host 'child' chips from diverse platforms, fostering seamless integration for multi-functional photonic architectures.

We present an optically packaged thin film lithium niobate device. We show that this packaged device is capable of cryogenic operation and is resistant to extreme thermal shock.
