abstract The next generation of optical networks requires the development of optical technology that supports high bandwidth, such as the coherent systems. The coherent detection allows the in-phase and quadrature components of a QPSK signal to be extracted as a result of the interference with a local oscillator. An integrated optics flexible 90 degrees hybrid coupler device based on a single organic-inorganic di-ureasil hybrid layer was fabricated using direct UV-laser writing. The demodulator exhibits a single input - multiple output port transfer function depending on the optical signal phase. This example demonstrates that di-ureasils are potential low-cost solutions for the fabrication of polarization controlling devices.
