Front Cover: Laser written circuits for quantum photonics (Laser Photonics Rev. 9(4)/2015)

Direct inscription of waveguides using ultrashort laser pulses allows for arbitrary three‐dimensional optics circuits, bringing unmatched design freedom to the field of on‐chip quantum photonics. The laser inscription technique allows rapid prototyping of a range of unique photonic circuits by simply translating a laser focus through a glass sample. In this review a detailed background of the applications of laser inscribed circuits to quantum photonics is provided with an emphasis on the novel designs permitted using this unique fabrication technique.
