2d layered graphene oxide films integrated with micro ring resonators for enhanced Nonlinear Optics
2020Co-Authors: Yunyi Yang, Roberto Morandotti, Sai T Chu, Brent E Little, Linnan Jia, Yuning Zhang, Baohua Jia, David J MossAbstract:Layered 2D graphene oxide (GO) films are integrated with micro-ring resonators (MRRs) to experimentally demonstrate enhanced Nonlinear Optics. Both uniformly coated (1-5 layers) and patterned (10-50 layers) GO films are integrated on complementary-metal-oxide-semiconductor (CMOS)-compatible doped silica MRRs using a large-area, transfer-free, layer-by-layer GO coating method with precise control of the film thickness. The patterned devices further employ photolithography and lift-off processes to enable precise control of the film placement and coating length. Four-wave-mixing (FWM) measurements for different pump powers and resonant wavelengths show a significant improvement in efficiency of ≈7.6 dB for a uniformly coated device with 1 GO layer and ≈10.3 dB for a patterned device with 50 GO layers. The measurements agree well with theory, with the enhancement in FWM efficiency resulting from the high Kerr Nonlinearity and low loss of the GO films combined with the strong light-matter interaction within the MRRs. The dependence of GO's third-order Nonlinearity on layer number and pump power is also extracted from the FWM measurements, revealing interesting physical insights about the evolution of the GO films from 2D monolayers to quasi bulk-like behavior. These results confirm the high Nonlinear optical performance of integrated photonic resonators incorporated with 2D layered GO films.

integrated sources of photon quantum states based on Nonlinear Optics
2017Co-Authors: Lucia Caspani, Roberto Morandotti, M Galli, Marco Liscidini, Daniele Bajoni, Chunle Xiong, Benjamin J Eggleton, David J MossAbstract:The ability to generate complex optical photon states involving entanglement between multiple optical modes is not only critical to advancing our understanding of quantum mechanics but will play a key role in generating many applications in quantum technologies. These include quantum communications, computation, imaging, microscopy and many other novel technologies that are constantly being proposed. However, approaches to generating parallel multiple, customisable bi- and multi-entangled quantum bits (qubits) on a chip are still in the early stages of development. Here, we review recent advances in the realisation of integrated sources of photonic quantum states, focusing on approaches based on Nonlinear Optics that are compatible with contemporary optical fibre telecommunications and quantum memory platforms as well as with chip-scale semiconductor technology. These new and exciting platforms hold the promise of compact, low-cost, scalable and practical implementations of sources for the generation and manipulation of complex quantum optical states on a chip, which will play a major role in bringing quantum technologies out of the laboratory and into the real world. Several new platforms are promising for generating and manipulating complex quantum optical states on a chip. Chip-based sources of quantum states of light are needed to bring quantum technologies out of the lab and into the real world, but such sources are still immature. David Moss at Swinburne University of Technology, Australia, and an international team have reviewed progress in developing and characterizing such sources. Waveguide, cavity and ring resonator devices made from Nonlinear materials such as silicon, silicon nitride, silicon oxynitride, Hydex and periodically poled lithium niobate offer scientists a rich variety of sources. Furthermore, many of these technologies can be integrated with silicon CMOS photonics, providing a path for building sophisticated, scalable optical integrated circuits for generating and manipulating quantum optical states for applications in quantum information processing and communications.

low power continuous wave Nonlinear Optics in doped silica glass integrated waveguide structures
2008Co-Authors: Marcello Ferrera, Roberto Morandotti, J E Sipe, Marco Liscidini, Luca Razzari, D Duchesne, Zhenyu Yang, Sai T Chu, Brent E LittleAbstract:Photonic integrated circuits are a key component1 of future telecommunication networks, where demands for greater bandwidth, network flexibility, and low energy consumption and cost must all be met. The quest for all-optical components has naturally targeted materials with extremely large Nonlinearity, including chalcogenide glasses2 and semiconductors, such as silicon3 and AlGaAs (ref. 4). However, issues such as immature fabrication technology for chalcogenide glass and high linear and Nonlinear losses for semiconductors motivate the search for other materials. Here we present the first demonstration of Nonlinear Optics in integrated silica-based glass waveguides using continuous-wave light. We demonstrate four-wave mixing, with low (5 mW) continuous-wave pump power at λ = 1,550 nm, in high-index, doped silica glass ring resonators5. The low loss, design flexibility and manufacturability of our device are important attributes for low-cost, high-performance, Nonlinear all-optical photonic integrated circuits. The ability to perform low-power, continuous-wave Nonlinear Optics, in particular four-wave mixing, is demonstrated in doped-silica-glass waveguide ring resonators. The device's low loss and ease of manufacture may make the approach suitable for Nonlinear all-optical photonic integrated circuits.
