分布ブラッグ反射器を用いた非平衡光放射の増強

抄録

When a voltage is applied to a semiconductor light emitting device such as an LED, a thermodynamically non-equilibrium state is generated, resulting in light emission that differs from the blackbody radiation of Planck's law. We have added a Distributed Bragg Reflector (DBR) to the conventional Thermophotonic (TPX) power generation system in order to achieve more efficient energy transport. In this study, we show that the radiation of TPX power generation is enhanced by the DBR by comparing an emitter with a combination of LED and DBR and an emitter with a single layer of LED.
