Reply to "Comment on "Normalization of quasinormal modes in leaky optical cavities and plasmonic resonators" " by E. A. Muljarov and W. Langbein

TL;DR

This paper systematically refutes the criticisms made in a comment on their previous work on quasinormal mode normalization, reaffirming their original methodology and clarifying overlooked aspects with additional calculations.

Contribution

The authors defend their original normalization method for quasinormal modes and clarify misunderstandings by providing further calculations linking different normalization approaches.

Findings

All claims of the comment are refuted as unjustified.

Important parts of the original argument were overlooked by the comment authors.

Additional calculations establish the connection between different normalization methods.

Abstract

We refute all claims of the "Comment on "Normalization of quasinormal modes in leaky optical cavities and plasmonic resonators" " by E. A. Muljarov and W. Langbein (arXiv:1602.07278v1). Based entirely on information already contained in our original article (P. T. Kristensen, R.-C. Ge and S. Hughes, Physical Review A 92, 053810 (2015)), we dismiss every point of criticism as being completely unjustified and point out how important parts of our argumentation appear to have been overlooked by the Comment Authors. In addition, we provide additional calculations showing directly the link between the normalizations by Sauvan et al. and Muljarov et al., which were not included in our original article.
