Case Study

BraggLive

Browser-based optical Fiber Bragg Grating simulator

BraggLive moves a numerically intensive optical simulation into the browser while preserving a responsive interface for exploratory modeling.

BraggLive optical simulation interface

Problem

Optical Fiber Bragg Grating simulation can be compute-heavy enough to interrupt interaction when implemented naively in client-side JavaScript.

My Role

Founder and developer across numerical implementation, frontend architecture, worker isolation, plotting, deployment, and product packaging.

Architecture

User Parameters
Web Worker Boundary
AssemblyScript Wasm Solver
Spectral Response Data
Plotly.js Visualization

Compute Model

Coupled-Mode Theory and Transfer Matrix Method solvers compiled to Wasm

Responsiveness

Heavy calculations isolated in Web Workers

Visualization

Interactive optical spectrum plotting and parameter exploration

Deployment

Zero-server-load model suitable for static hosting

Decision

Compile numerical solvers to Wasm and isolate them behind a Web Worker boundary

Tradeoff

Favor portable client-side execution and zero server load over server-side control
