Current technology for polarization beam splitters is limited to extinction ratio of around 25 decibels which is high enough to affect high-speed data transmission. Researchers in Singapore conceptualized design for a three-waveguide device and verified its feasibility on computer simulation. They confirmed its vastly improved extinction ratio of 40 decibel, representing a further 30-fold reduction in polarization crosstalk. The research is a breakthrough in improving high-performance data transmission systems, as well as applications in quantum computing… read more. TECHNICAL ARTICLEÂ
