光子BEC的偏振动力学
Polarization dynamics in a photon BEC
摘要：
先前已经表明，染料填充的微腔可以产生光子的玻色-爱因斯坦凝聚体。通过染料分子的重复吸收和再发射，光子的热化是可能的。本文从理论上探讨了该系统中光的偏振行为。我们发现，在不同的空间模式的光之间的近完全热化，热化的偏振态预计一般是不完整的。我们发现，从低于阈值以上的极化程度的变化显着，并解释了所有相关的材料参数的极化的依赖性。
英文摘要：
It has previously been shown that a dye-filled microcavity can produce a Bose-Einstein condensate of photons. Thermalization of photons is possible via repeated absorption and re-emission by the dye molecules. In this paper, we theoretically explore the behavior of the polarization of light in this system. We find that in contrast to the near complete thermalization between different spatial modes of light, thermalization of polarization states is expected to generally be incomplete. We show that the polarization degree changes significantly from below to above threshold, and explain the dependence of polarization on all relevant material parameters.
