| Photonic integrated circuits (PICs) have so far got a quite modest integration level. There is a growing interest on the concept of PICs having enhanced functionality while keeping or moderately increasing their complexity. One possible route to this goal is to develop active waveguides within the PICs, by including electrooptical devices that can control several parameters of the propagating light. In this work we have explored light manipulations achievable by insertion of a liquid crystal slab in a tilted trench into the light path of a number of waveguides. This simple device has demonstrated several functionalities depending on the tilt angle, the refractive indices of the waveguides, the liquid crystal and the relative position of the input and output waveguides. Some examples are polarizers, polarization interchanger, optical switch and polarization switch. If the trench is conveniently pixelized, the device can even be employed as a simple optical cross-connect | |
