We demonstrate enhanced absorption in a photonic crystal resonator (PCR) coupled with an optical microfiber. Enhanced absorption is based on coherent perfect absorption (CPA) that is time-reversed lasing. The PCR is fabricated on a silicon membrane with optimized parameters obtained from a numerical simulation. In an experiment, we observed 72% of absorption for the PCR with the optimized parameters. We also verified numerically that the absorption required for CPA can be tuned by changing the distance between the PCR and the optical microfiber.

通过与微纤维耦合的光子晶体谐振器中的相干控制增强吸收

我们展示了光子晶体谐振器(PCR)与光学超细纤维耦合中增强的吸收。增强的吸收基于时间反转激光的相干完美吸收(CPA)。PCR是在硅膜上制造的,具有从数值模拟获得的优化参数。在一个实验中,我们观察到具有优化参数的PCR吸收率为72%。我们还通过数值验证了通过改变PCR和光学微纤维之间的距离可以调节CPA所需的吸收率。
