Abstract
We reply to the comment [Optica 8, 824 (2021)OPTIC82334-253610.1364/OPTICA.410990] on our recent article [Optica 7, 323 (2020)OPTIC82334-253610.1364/OPTICA.381175], where we exploited time-dependent metamaterials to achieve antireflection temporal coatings in the time domain. Clearly our approach has equivalences, but also differences, with its spatial analogue due to some fundamental differences in the physics behind temporal and spatial boundaries. In this context, we fully stand by our original claims and remark that a comparison and analogy between both worlds can be made with the understanding that each approach provides opportunities for different applications. Here, we provide a comprehensive and detailed reply in order to address the claims made in the comment.
