Аннотация
Optical computing using supercontinuum generation in photonic crystal fibers is investigated for machine learning tasks. The study reveals the significance of nonlinear pulse propagation dynamics and the need to balance optical nonlinearity for efficient performance. By analyzing octave-spanning supercontinua, the study highlights challenges such as loss of dataset variety due to many-to-one mapping. The research provides insights into designing energy-efficient photonic neural network architectures by understanding the interplay between nonlinear dynamics and optical computing. Various datasets like Sinc regression, iris classification, and liver disease classification are used to test the PCF-based photonic neural network's performance. The study showcases how adjusting peak powers and propagation distances affect machine learning outcomes. Results indicate that fine-tuning optical nonlinearity is crucial to maintain a balance between dimensionality expansion and model performance.

Our results show that generating just one image with a generative AI model uses as much energy as charging an average cellphone.
Optical computing offers advantageous operations like Fourier transform, convolution, and matrix multiplication intrinsically using passive components.
Linear Discriminant Analysis (LDA) is utilized to visualize how different classes of data are separated by dimensionality expansion provided by optical nonlinear dynamics.
The Sinc regression dataset consists of 500 linearly spaced data points ranging from -π to π.
For the liver disease dataset, a classification accuracy of 86.57% is achieved with only Linear SVC.
The accuracy of the photonic neural network reaches 98.61% for a peak power of 2.6 kW in the liver disease dataset classification task.
When peak power increases to 10 kW, the accuracy of the model deteriorates to 91.98% due to mixing classes within the dataset.
