ITO ENZ photonics: from modulators to optical limiters (Conference Presentation)
Author(s): Volker J. Sorger

Paper Abstract

The material class of transparent conductive oxides features a variety of properties that are interesting and useful for optical and opto-electronic applications. ITO belonging to this class has shown to be either processed (Gui et al, Nat. Sci. Rep. 2019), or electro-statically-biased (Sorger et al., Nanoph. 2012) into the ENZ regime. Here, I review our latest work including; (1) ITO ENZ material deposition control, (1) the first ITO-based phase-shifters in silicon photonics with VpL=0.5V-mm (Amin et al, APL 2018) and 0.06V-mm performance (Amin et al, arXiv 1907.11131 2019), (2) electro-optic nonlinear activation function in feed-forward photonic neural networks (Amin et al, APL Mat. 2019), (3), optical-phase array in silicon-ITO photonics for GHz-fast beam steering, (4) a metatronic circuit board towards an analog photonic computer for PDEs, and (5) strong nonlinearity in ENZ ITO showing ~10dB of optical limiting.
