Abstract

Recent breakthroughs in photonics design, along with new nanofabrication approaches and heterogeneous integration play crucial roles in building photonics for applications including optical interconnects and quantum technologies. The implementation of scalable quantum systems is the most dramatic example of this effort, as it requires new photonic materials and device functionalities, together with stringent device performances. Towards this goal, the platforms based on color centers in diamond and silicon carbide have been considered promising candidates, because of their optically interfaced spin qubits, high speed and high fidelity quantum gates, and high quality photonics. While these platforms have usually been studied in the context of quantum networking, recent demonstration of coherent interactions of multiple qubits inside a single silicon carbide resonator has established this system as a promising candidate for quantum simulation and possibly even quantum computing.
However, truly scalable systems require integration of all passive and active photonic devices on the same chip, including sources. Following the same advances in design, fabrication, and heterogenous integration, even Titanium:sapphire laser, the workhorse of optics laboratories, can be miniaturized into sub-cubic centimeter volume together with its pump, and without any loss of performance.
