Research Progress on Integrated Acousto-Optic Modulators Based on Subwavelength Acoustic Waveguides
摘要
Abstract
In recent years,integrated acousto-optic modulators based on sub-wavelength acoustic waveguides have made significant progress in the fields of optical communications,quantum information processing,and optical computing.By restricting acoustic and optical waves to the sub-wavelength scale,the acousto-optic interaction strength has been significantly enhanced,achieving high modulation efficiency and low power con-sumption.Materials such as lithium niobate(LiNbO3)and sapphire(Al2O3)are widely used in the design of sub-wavelength acoustic waveguides due to their excellent optical and acoustic properties and good compatibility with optical waveguides.The high electro-optical effect of lithium niobate makes it an ideal material for inte-grated acousto-optic modulators,while sapphire excels in high power applications due to its extremely high ther-mal conductivity and mechanical strength.Meanwhile,the proposal of non-suspended waveguide design has become a major breakthrough in this field,effectively reducing waveguide loss and providing higher integration.In this paper,we first introduced the basic principles of integrated acousto-optic modulators based on sub-wavelength acoustic waveguides,and then reviewed recent key research results in this field.Finally,we explored its potential applications in microwave-optical wave conversion and isolators,and outlined future research trends.关键词
