Laser Diode to Fiber Coupling Analysis

This knowledge base article discusses how to use FRED to accurately model the coupling from a ball-lens capped semiconductor laser diode to a single mode fiber – an optical system common in optical fiber communication applications. This model demonstrates FRED’s capability to propagate coherent fields, its accurate Laser Diode Beam source type and its ability to calculate fiber coupling efficiency.

Longitudinal, horizontal and angular alignment sensitivity of the fiber position is studied via embedded scripts.
