3. Applications
This hybrid fiber optic array is primarily used in complex integrated optical systems, especially in scenarios requiring the simultaneous processing of different types of optical signals:
Optical Devices/Modules: Used for packaging multifunctional integrated optical modules.
Coherent Optical Transceivers: This is the most typical application scenario. Coherent communication typically requires both the local oscillator light (polarization maintained by PM fiber) and the signal light (transmission by SM fiber) to be coupled into the chip simultaneously.
