Integration of quantum optical devices with other quantum technologies onto a compact and scalable platform is critical for widespread applications of quantum information science. An integrated quantum optoelectronic circuit would bring these technologies together on a single chip and enable mass-producible, robust, and low cost devices for “real world” applications.
Silicon photonics has become the incumbent technological platform for integrated photonics devices due to its compatibility with CMOS electronics, ease of fabrication, and the availability of a large array of standard devices. However, it has significant drawbacks for applications in quantum information science; indirect bandage, no second order nonlinearity, and high propagation losses.
In this talk, I will present current efforts on the next generation of integrated photonics which could lead to integrated quantum optoelectronic circuits. We will discuss our work on coupling external light sources to a photonic chip with low loss, enabling a second order nonlinearity in CMOS compatible materials, and give an example of quantum inspired phase measurements in a photonic platform.
