| Popis: | Though in many applications in optoelectronics light amplitude is the most important parameter for carrying the information flow, in some cases the phase or the polarisation of the guided waves is more relevant (optical sensors, Faraday rotators, coherent telecommunications...). Here we report on a polarisation beam splitter based on a Y-fed directional coupler with propagation along the Z axis of a LiNbC>3 crystal. 1. INTRODUCTION Integrated optics has proven its large potential of applications in many fields such as telecommunications, optical sensing, signal processing, etc.. Most of time, the amplitude of the guided light is the parameter where the information is printed by the use of external modulators like switches or MACH ZEHNDER interferometers. But in some cases, the phase or the polarisation of the propagating waves is a more relevant quantity to be measured. Since it may be more difficult to make an amplitude type modulator insensitive to the incoming light state of polarisation, it turns out that devices capable of controlling this latter parameter could find a large range of applications. Here we report on a polarisation beam splitter based on a Y-fed directional coupler with propagation along the C axis of an active substrate of lithium niobate LiNb03. |
