3D stacking has the potential to revolutionize photonics. A new study from scientists at the University of Connecticut shows that by stacking photonic crystals on top of each other, the thermal impact of the crystals can be significantly reduced. The research, published in the journal Optics Express, suggests that 3D stacking of photonic crystals can be used to reduce the heat energy generated by the crystals, and therefore, reduce their temperature. This could lead to improved performance of photonic systems and devices. The researchers used a combination of simulation and experiment to demonstrate the thermal impact of 3D stacking on photonic crystals. They found that the temperature of the stacked crystals was significantly lower than that of the single-layer crystals. The study also showed that the temperature reduction was due to the increased thermal conductivity of the stacked crystals. The findings could have far-reaching implications for the design of photonic systems and devices.
