论文摘要
Aluminum gallium arsenide-on-insulator (AlGaAsOI) exhibits large $χ^\left(2\right)$ and $χ^\left(3\right)$ optical nonlinearities, a wide tunable bandgap, low waveguide propagation loss, and a large thermo-optic coefficient, making it an exciting platform for integrated quantum photonics.借助Algaasoi中建立的量子光源的量子，下一步是开发芯片尺度量子光电电路的关键构建块。在这里，我们通过演示边缘耦合器，3-DB拆分器，可调干涉仪和波导交叉口，扩展了藻类的量子光子工具箱，其性能可与硅和硅二硝酸盐量子光子平台相当。作为演示，我们通过不平衡的干涉仪来消除型光子速度，从而铺平了光子量子计算和信息应用的超高效和高速芯片尺度的途径。
Aluminum gallium arsenide-on-insulator (AlGaAsOI) exhibits large $χ^\left(2\right)$ and $χ^\left(3\right)$ optical nonlinearities, a wide tunable bandgap, low waveguide propagation loss, and a large thermo-optic coefficient, making it an exciting platform for integrated quantum photonics. With ultrabright sources of quantum light established in AlGaAsOI, the next step is to develop the critical building blocks for chip-scale quantum photonic circuits. Here we expand the quantum photonic toolbox for AlGaAsOI by demonstrating edge couplers, 3-dB splitters, tunable interferometers, and waveguide crossings with performance comparable to or exceeding silicon and silicon-nitride quantum photonic platforms. As a demonstration, we demultiplex photonic qubits through an unbalanced interferometer, paving the route toward ultra-efficient and high-rate chip-scale demonstrations of photonic quantum computation and information applications.
