摘要:

光学微谐振器近年来在光子学领域引起了越来越多的关注。它们的应用范围从量子电动力学到光学电信系统的传感器和滤波设备,它们可能成为一个重要的组成部分。在谐振器中集成非线性和电光特性代表了一个非常刺激的挑战,因为它将包含新的和更先进的功能。锂离子电池是一种优秀的候选材料,是电光和非线性光学应用的既定选择。在这里,我们报告的第一个实现的光学微型谐振器在亚微米薄膜的锂离子。高折射率对比度薄膜是用改进的晶体离子切片和键合技术,使用苯并环丁烯。环具有半径R=100 μ m,并且它们的透射光谱已经使用电光效应进行了调谐。这些结果为锂酸盐在芯片级集成光学器件和非线性光学微腔中的应用开辟了新的前景。

英文摘要:

Optical microresonators have recently attracted a growing attention in the photonics community. Their applications range from quantum electro-dynamics to sensors and filtering devices for optical telecommunication systems, where they are likely to become an essential building block. The integration of nonlinear and electro-optical properties in the resonators represents a very stimulating challenge, as it would incorporate new and more advanced functionality. Lithium niobate is an excellent candidate material, being an established choice for electro-optic and nonlinear optical applications. Here we report on the first realization of optical microring resonators in submicrometric thin films of lithium niobate. The high index contrast films are produced by an improved crystal ion slicing and bonding technique using benzocyclobutene. The rings have radius R=100 um and their transmission spectrum has been tuned using the electro-optic effect. These results open new perspectives for the use of lithium niobate in chip-scale integrated optical devices and nonlinear optical microcavities.
