Fiber optics are critical parts of modern telecommunication infrastructure and many other applications. Their ability to transmit data at high-bandwidths and with small loss has enabled the global internet as we know it. Optical systems that couple light from a source fiber into a receiving fiber are important parts of this application chain.
Quadoa provides several capabilities that enable simulation of fiber optic coupling. Source properties can be easily defined using fiber specs such as NA, MFD, and M2 factors. Receiving fiber properties can be similarly defined and coupling efficiency using overlap integrals can be computed. These calculations can be optimized to maximize coupling efficiency and toleranced to determine manufacturing impacts.
