Formal methods have been used classically for the verification of software, circuits or protocols. In most cases, verification deals with an abstraction of the underlying physical system (e.g., software verification does not involve the modelization of a computer, circuit verification does not model semi-conductors). We propose to try to verify such physical systems, focusing in particular on optical systems which have several applications (from fiber optics to quantum computer implementations). This requires the formalization of physical concepts (e.g. ray of light, lens, electromagnetic wave or photon), of the physical principles that govern them (e.g., Fermat's principle or Maxwell equations), and the derivation, from these principles, of various laws that are useful for the verification of concrete systems (e.g., Snell's law or the Uncertainty principle). We will explain how these concepts and principles can be successfully formalized (in HOL-Light) as well as the limitations of this approach.
