Abstract

We present the first experimental demonstration of coherent perfect absorption (CPA) in an integrated device using a silicon racetrack resonator at telecommunication wavelengths. Absorption in the racetrack is achieved by Si-ion-implantation, allowing for phase controllable amplitude modulation at the resonant wavelength. The device is measured to have an extinction of 24.5 dB and a quality-factor exceeding 3000. Our results will enable integrated CPA devices for data modulation and detection.

摘要

我们展示了在电信波长下使用硅环形谐振器的集成器件中相干完美吸收（CPA）的首个实验演示。通过硅离子注入实现环形谐振器中的吸收，从而在谐振波长处实现相位可控的幅度调制。测得该器件的消光比为24.5 dB，品质因数超过3000。我们的结果将推动用于数据调制和检测的集成CPA器件的发展。
