摘要:

集成薄膜锂酸盐(TFLN)光子学已成为实现高性能芯片级光学系统的一个有前途的平台。特别重要的是TFLN电光调制器具有高线性度,低驱动电压和低传播损耗。然而,全集成系统要求在TFLN芯片上集成高功率、低噪声、窄线宽的激光器。在这里,我们实现了这一目标,并展示了TFLN平台上的集成高功率激光器,波导中的光功率高达60 mW。我们使用这个平台来实现一个高功率的发射机组成的电泵浦激光器与50 GHz的调制器集成。

英文摘要:

Integrated thin-film lithium niobate (TFLN) photonics has emerged as a promising platform for realization of high-performance chip-scale optical systems. Of particular importance are TFLN electro-optic modulators featuring high-linearity, low driving voltage and lowpropagation loss. However, fully integrated system requires integration of high power, low noise, and narrow linewidth lasers on TFLN chip. Here we achieve this goal, and demonstrate integrated high-power lasers on TFLN platform with up to 60 mW of optical power in the waveguides. We use this platform to realize a highpower transmitter consisting an electrically-pumped laser integrated with a 50 GHz modulator.
