Abstract

The manipulation of the phase of classical and quantum light is a major key to quantum photonics [1]. Integrated optics has several advantages over bulk optical systems, most notably in robustness, handling and size. Writing three-dimensional waveguides circuits into transparent materials using an ultrafast laser is thereby a new emerging technology [2; 3] with possible applications in quantum communication [4], and quantum computing [5]. In our work, we experimentally demonstrate the high-precision manipulation of the optical phase of classical and quantum light, using a generalized directional coupler.
