When two experienced and accomplished researchers collaborate to deliver a book elucidating an exciting emergent field of activity, one hopes for an enjoyable and educative reading experience. This book provides exactly that.

The authors successfully convey the basic principles of the area of endeavour, including a succinct summary of the material platforms suitable for developing programmable integrated photonics. On that solid foundation the book develops, in a methodical manner, detailed implementations of the novel functionality provided by this new technology. The underlying theory of the approach is carefully presented before offering a comprehensive discussion of the startling range of devices made possible by this approach. The topicality of the subject matter is underlined by the identified scope for applications, including classical and quantum systems. This is the go-to book for current and future researchers in this field.
