Piggott et al. reply

Our recent Letter1 reports the first experimental demonstration of our 'objective-first' inverse design method2 applied to a practical device. As such, the introduction in our Letter was intended to provide a brief but broad overview of both computational design methods and demonstrated structures. Our previous works2,3 provide a more thorough overview of the field. Sigmund et al. have raised concerns regarding our paper4. For the benefit of the reader, we provide the following broad historical survey of computational electromagnetic design, and place the objective-first method in that historical context.
