Abstract

Nonlinearity provides a key functionality for a plurality of devices, effects, and systems. In this talk I show that both all-optical and electro-optical nonlinearity can be strongly enhanced at the slow-light effect epsilon-near-zero (ENZ). I share our recent experimental demonstrations including (a) temporally tailoring ENZ nonlinearity (Optics Letters 2020), (b) spectrally 400nm broadband ENZ enhancement, (b) GHz-fast yet micrometer-compact electro-optic modulator within a MZI-Silicon-ITO hybrid platform (OPTICA 2020, Scientific Reports 2021), and (c) Kramers-Kronig-enhanced electro-absorption modulator (NANOPHOTONICS 2019). Together, these technologies show that monolithic integration of TCO into PICs provides functionality beyond Silicon photonics with application in datacom, sensing, and neuromorphic computing.

巨大和超快非线性与ENZ光子
非线性为许多器件、效果和系统提供了关键功能。在这次演讲中,我展示了在慢光效应下,全光学和电光非线性都可以被强烈增强。我分享我们最近的实验演示,包括(a)暂时定制ENZ非线性(光学快报2020),(b)光谱400nm宽带ENZ增强,(b)在mzi -硅- ito混合平台内的ghz快但微米紧凑的电光调制器(OPTICA 2020,科学报告2021),以及(c)克列默斯-克朗格增强型电吸收调制器(NANOPHOTONICS 2019)。总之,这些技术表明,将TCO单片集成到pic中,可以在数据通信、传感和神经形态计算方面提供硅光子学之外的功能。
