Integrated Photonic Neural Networks with Arbitrary Capabilities
Continued economic and societal growth depend on complex, multi-functional, and advanced circuitry for accelerating connection to large volumes of data. Photonic integrated circuits represent a critical class of devices that enable this data access and processing capabilities. So far, photonic circuits have been designed using either traditional methods, or machine-based optimizers that are programmed to determine device geometries from scratch. While these approaches are viable for certain basic categories of photonic functions, more complex and custom applications require development of more advanced and high-performance photonic design methods in order to meet the needs of these future applications, and to standardize the photonic design ecosystem across multiple different industries. To this end, the overall goal of the NeuroPhotonics project is to build an experimentally verified photonic neural network device architecture and framework, for the design of photonic integrated circuits with arbitrary on-chip capabilities. Using arrays of customized photonic interferometers, this framework enables previously elusive optical functionality including arbitrary combinations of ultra-wideband, fabrication-tolerant, and wavelength-selective optical responses. The overall objectives include creating an open-source software package for rapidly extracting guided wave parameters, building a multi-purpose design framework for universal photonic neural network architectures for desired arbitrary functionality, experimentally demonstrating input-output mapping capabilities by fabricating and characterizing these photonic networks, and bridging project innovations with industry through a post-project innovation management plan for commercialization of the framework. This presented design platform provides a tractable path towards the systematic design of large-scale photonic systems with custom and broadband power, phase, and dispersion profiles for use in multi-band optical applications including high-throughput communications, quantum information processing, and medical/biological sensing.

Project objective
As data generation and transfer rates have grown rapidly over the last decades, integrated photonic systems have become the key technology enabling modern communication systems. In order to sustain future economic and societal growth, continued development of arbitrarily complex and multi-functional integrated photonic systems is therefore imperative. Traditional design of these systems relies on determining device geometries using analytical electromagnetics, after which various parameters are optimized. In contrast, the flexibility for more complicated optical functionality is currently only possible with “blank-slate” optimization routines. In these algorithms, the device structure is determined by searches through thousands of degrees of freedom, which is computationally prohibitive when targeting arbitrarily complex functionality with larger devices. To this end, this project will develop an artificial intelligence-based, universal photonic neural network architecture and its optimization framework to enable and experimentally demonstrate arbitrary photonic capabilities on-chip. For the first time, this novel approach will allow solutions for designer-specified operations including arbitrary combinations of wavelength and polarization-specific transfer functions. Resulting devices will be fabricated and characterized to demonstrate previously elusive on-chip functionality, and for rapid adoption and widespread use. Customer needs in communications and sensing applications will be specifically targeted through an industrial secondment, and a structured innovation management/commercialization plan. This framework and its industrial use represent a vast leap towards universal integrated photonic design for advancing European capability and economic drivers through innovation in future optical systems. As such, the fellowship will transform my career towards future leadership at the intersection of academic research and industrial innovation.
