Abstract: An improved time-domain beam propagation method based on the propagation of a quasi-rectangular pulse is proposed to analyze and optimize the integrated components in which wide-angle of ...

Abstract: We present an optical modeling approach for calculating vertical-cavity surface emitting laser (VCSELs) modes based on the bidirectional beam propagation method. Compared with existing ...

This project implements a Multi-Layer Perceptron (MLP) from scratch using Python and NumPy for classification tasks ... For each batch, forward propagation is used to generate predictions, ...

Pyrefly is a fast type checker for Python. It's designed to replace the existing Pyre type checker at Meta by the end of 2025. This README describes basic usage. See the Pyrefly website for full ...
