Graded Index Couplers: A Universal Interface for Photonic Integrated Circuit Packaging

A silicon oxynitride graded index coupler was designed to connect silicon nitride waveguides on separate chips, demonstrating a simulated coupling loss of 0.45 dB and a 1-dB alignment tolerance of ± 2.3 µ m at 1550 nm for an 11 µ m vertical chip-to-chip gap.

Abstract

A silicon oxynitride graded index coupler was designed to connect silicon nitride waveguides on separate chips, demonstrating a simulated coupling loss of 0.45 dB and a 1-dB alignment tolerance of ± 2.3 µ m at 1550 nm for an 11 µ m vertical chip-to-chip gap.
