Wavelength selective switch

Abstract

This application discloses a wavelength selective switch, including an optical fiber module, an optical chipset, and an optical switching module. The optical chipset includes one or more optical chips. The optical fiber module emits an incident light beam into the optical chipset. The incident light beam is split into multiple dispersive beams with different wavelengths within the optical chipset. These dispersive beams exit from different positions within the optical chipset and are emitted into the optical switching module. After reflection by the optical switching module, they return to the optical chipset. The multiple dispersive beams are then combined into a single signal beam within the optical chipset. This signal beam exits the optical chipset and returns to the optical fiber module. The technical solution of this application significantly simplifies the coupling and adjustment of optical lenses, eliminates inherent aberrations, and reduces product size. During manufacturing, based on the characteristics of integrated optics, it is suitable for large-scale production, resulting in more efficient capacity replication and ultimately enabling low-cost reconfigurable optical networks to extend from the backbone network to the aggregation layer and data centers.
