Topic Information

Dear Colleagues,

The field of silicon photonics has rapidly evolved over the last few years, supported by advances in the maturity of the technology, design tools, and methods employed. The quest for new ideas and concepts to deploy low-cost, compact, and power-efficient photonic circuits with a high wafer yield and robustness that are able to meet the requirements in several application domains has triggered frenetic activity worldwide. Presently, photonic circuit technology has diversified its number of available platforms. Despite the fact that indium phosphide (InP) and silicon-on-insulator (SOI) platforms are still considered the warhorses of integrated photonics in terms of maturity and the deployment of active (InP) and passive (SOI) components, other alternatives such as germanium-on-silicon, silicon nitride-on-insulator, or hybrid solutions combining different functional materials and Si are gaining momentum. A representative example is the hybrid III-V/Si platform, which has been used to develop on-chip tunable lasers for wavelength division multiplexing purposes. Indeed, the possibility to integrate several materials in a single photonic technology represents an attractive playground scenario to explore novel functionalities not available before in monolithic approaches. In this regard, the implementation of multifunctional photonic circuits that collect, transmit, or reconfigure data in real-time conditions while interacting with their environment may open the route for a new class of photonic circuits with a wide range of possibilities and applications. This Topic will focus on recent advancements in hybrid and heterogeneous photonic circuits covering materials, processing techniques, and the implementation of novel components, devices, and circuits employing diverse materials to enable multifunctional photonic platforms. With a combination of invited and contributed papers, this Topic will survey the state-of-the-art of hybrid and heterogeneous photonic circuit technology.

In this study, a compact and low-power-consumption quantum random number generator (QRNG) based on a laser diode and a hybrid chip with integrated silicon photonics is proposed and verified experimentally. The hybrid chip’s size is 8.8 × 2.6 × 1 mm3, and the power of the entropy source is 80 mW. A common-mode rejection ratio greater than 40 dB was achieved using an optimized 1 × 2 multimode interferometer structure. A method for optimizing the quantum-to-classical noise ratio is presented. A quantum-to-classical noise ratio of approximately 9 dB was achieved when the photoelectron current is 1 μA using a balance homodyne detector with a high dark current GeSi photodiode. The proposed QRNG has the potential for use in scenarios of moderate MHz random number generation speed, with low power, small volume, and low cost prioritized. Full article
