Tunable Microwave Resonators for Superconducting Electro-optic Devices

Key Points

• This work demonstrates over 500 MHz of frequency tuning in superconducting microwave resonators with a bulk permanent magnet.
• The resonators achieved over 100 MHz of tuning with planar coils under moderate magnetic fields of less than 5 mT.
• Designed for integration, these superconducting resonators utilize photolithography methods for manufacturing.
• The findings highlight the potential for enhancing electro-optic devices through effective resonator tuning.
