The router can work in the spectral range used in step-index polymer optical fiber networks (400-700 nm) with low wavelength and temperature dependences. The theoretical design is fast and simple and has good agreement with experimental results. Experimental crosstalk is lower than -18.68 dB for both outputs, even with thermal variations of 10 °C. Performance improvement with respect to previously reported devices with similar structure has also been analyzed.7application/pdfeng© 2014 ElsevierAtribución-NoComercial-SinDerivadas 3.0 EspañaLiquid crystal displaysMultiplexingOptical communicationPlastic optical fibersFiber optics communicationLiquid crystal devicesOptical routersPolarization-selective devicesVariable optical splittersEngineering main headingMultiplexingresearch articleElectrónicaIngeniería IndustrialÓptica10.1016/j.optcom.2014.07.065open access28115287Optics Communications333AR/0000016356
