On-Chip 4f-System-Based Arbitrary-Mode Spot Size Conversion
2020 EUROPEAN CONFERENCE ON OPTICAL COMMUNICATIONS (ECOC)(2021)
Abstract
An on-chip spot size converter is proposed and demonstrated for arbitrary modes, using a pair of lenses in a 4-f imaging system configuration. The device length can be reduced by 72% compared to linear taper at a same inter-mode crosstalk level.
