WebConsidering the high integration of Silicon photonics chip, it is better to use a fiber array for chip coupling. Besides, the waveguide of the photonics chip is small, it cannot be coupled with regular single-mode fiber directly. Therefore, some transition processing is needed. WebOn-chip photonic systems play crucial roles in nanoscience and nanoapplications, but coupling external light to these subwavelength devices is challenging due to a large mode mismatch.
