Inverse-Designed Vertical Turning Structures for Ultra-Dense 3D Heterogeneous Integration

We design topology optimized ultra-compact (3μm x 3μm) structures enabling coupling of in-plane waveguides to vertical waveguides. The photonic up-turn (1.66dB loss) and down-turn (1.26dB loss) structures advance ultra-dense chip-to-chip 3D heterogeneously integrated systems.

Abstract

We design topology optimized ultra-compact (3μm x 3μm) structures enabling coupling of in-plane waveguides to vertical waveguides. The photonic up-turn (1.66dB loss) and down-turn (1.26dB loss) structures advance ultra-dense chip-to-chip 3D heterogeneously integrated systems.
