High-Performance Thin Film Lithium Niobate Electro-Optic Modulator By Embedding Structure
Electro-optic modulators with low driving voltage and wide bandwidth are critical for advanced analog and digital communication systems. Improving the modulation efficiency of thin-film lithium niobate (TFLN) modulators is essential to reducing drive voltage and device length, thereby enabling compact chip integration and enhanced modulation bandwidth. This work introduces a novel TFLN modulator featuring an embedded dual capacitance-loaded traveling-wave electrode (EDC-TWE) to achieve superior electro-optic modulation efficiency and minimized optical loss. The fabricated modulator, with a 10-mm-long modulation region, achieves a half-wave voltage of 1.45 V and an electro-optic modulation bandwidth exceeding 40 GHz, demonstrating its potential for high-performance optical communication applications.
期刊介绍:
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
