Abstract

Broadband, compact electro-optic modulator is one of the key components in optical communication networks and microwave photonic systems. Here, this paper reports a thin-film lithium niobate electro-optic modulator with a 3 dB electro-optic bandwidth greater than 50 GHz after encapsulation, and discusses the electro-optic response and thermo-optic phase-shifting performance of the device. The modulator chip has a 3 dB electro-optic bandwidth greater than 67 GHz, and the fully encapsulated device has a small size (31 mm

$\times 10$

$\times 5.3$

mm) while having a high electro-optic bandwidth of up to 51 GHz and an excellent half-wave voltage length product as low as 2.5 V

$\cdot$

cm. The DC bias is thermally shifted with a 2.3V half-wave voltage for reliable and stable bias characteristics.

期刊介绍： The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
