基于腔机电系统中光子和声子的光子晶体管器件

A photonic transistor device based on photons and phonons in a cavity electromechanical system

Cheng Jiang, Ka-Di Zhu

摘要:

提出了一种基于腔机电系统中光子和声子的光子晶体管方案,该系统由超导微波腔和纳米机械谐振器耦合组成。光子传播的控制是通过微波场(光子)和纳米机械振动(声子)的相互作用来实现的。通过计算的信号场的透射谱,我们表明,信号场可以有效地衰减或放大,这取决于第二个“门控”(泵)字段的功率。这种方案可能是单光子晶体管的一个有前途的候选者,并为电信和量子信息技术中的许多应用铺平了道路。

英文摘要:

We present a scheme for photonic transistors based on photons and phonons in a cavity electromechanical system, which is consisted of a superconducting microwave cavity coupled to a nanomechanical resonator. Control of the propagation of photons is achieved through the interaction of microwave field (photons) and nanomechanical vibrations (phonons). By calculating the transmission spectrum of the signal field, we show that the signal field can be efficiently attenuated or amplified, depending on the power of a second `gating'(pump) field. This scheme may be a promising candidate for single-photon transistors and pave the way for numerous applications in telecommunication and quantum information technologies.
