Brief
The article proposes and experimentally validates a method for fabricating miniaturized and integrated fiber array collimators using a plano-convex microlens array, demonstrating good collimation characteristics with a measured far-field divergence angle within the design tolerance.
Summary
The article "Design of fiber array collimator and measurement of its divergence angle" proposes a new method to fabricate small and integrated fiber array collimators using plano-convex microlens arrays, overcoming limitations of traditional methods. The study includes theoretical analysis, fabrication of a four-element array, and experimental measurement of the far-field divergence angle, which showed good collimation characteristics and 一致性 (consistency) within the design specifications. This approach aims to meet the growing demands for miniaturization and integration in optical fiber communication systems
