The next generation of photonic circuits will require programmable, subnanosecond, and energy-efficient components on a scalable platform for quantum and neuromorphic computing. Here, we present subnanosecond electrical control of highly nonlinear light-matter hybrid quasi-particles, called waveguide exciton-dipolaritons, in a highly scalable waveguide-on-chip geometry, and with extremely low power consumption. Our device performs as an optical transistor with a GHz-rate electrical modulation at a record-low total energy consumption <8 fJ/bit and a compact active area of down to 25 μm. This work establishes waveguide-dipolariton platforms for scalable, electrically reconfigurable, ultralow power photonic circuits for both classical and quantum computing and communication.
下一代光子电路将需要在可扩展平台上具备可编程、亚纳秒级且节能的组件，以用于量子和神经形态计算。在此，我们展示了在高度可扩展的片上波导几何结构中，对一种称为波导激子 - 偶极子的高度非线性光 - 物质混合准粒子进行亚纳秒级电控制，并且功耗极低。我们的器件作为一个光学晶体管，在创纪录的低总能耗<8 fJ/比特以及低至25μm的紧凑有源面积下，实现了GHz速率的电调制。这项工作为用于经典和量子计算及通信的可扩展、电可重构、超低功耗光子电路建立了波导 - 偶极子平台。
