Automating Photonic Integration for Next-Generation Applications

Abstract

Vanguard Automation's fully automated technologies like Photonic Wire Bonding and facet-attached micro-optical elements are advancing photonic integration and packaging. Their solutions enable seamless transitions from prototyping to volume production.

Introduction

The rapid pace of innovation in photonic integrated circuits is increasing the need for faster, more scalable solutions. Vanguard Automation aims to accelerate photonic development through fully automated nano-fabrication processes for integration and packaging. Their portfolio of technologies facilitates the transition from prototyping to high-volume manufacturing.

Enabling Scalable Photonic Integration

Vanguard’s Photonic Wire Bonding (PWB) utilizes advanced 3D nano-printing to create low-loss 3D connections between optical components. This provides design flexibility and automation. Their facet-attached micro-optical elements allow low-loss coupling and wafer-level probing. Together, PWB and faceted elements advance photonic packaging and assembly across platforms.

Note: It comprises the automated 3D lithography-based nano fabrication unit Sonata 1000 and the automated pre- and postprocessing unit Reprise 1000. The systems are equipped with Vanguard’s BrightWire3D software, enabling highly precise detection and on-the-fly trajectory calculations. Vanguard’s own photoresists (Vanguard VanCore series), standard process development, as well as product support and engineering services complete Vanguard’s solution from prototyping to high-volume production.

Streamlining Diverse Photonic Integration

Integrating various photonic components from different material systems poses challenges. Hybrid modules may combine lasers, amplifiers, silicon/nitride passives, lithium niobate devices, and specialty fibers. Vanguard’s solutions address the complex integration needs arising from diverse optical properties and materials. Faceted elements and precision PWB alignment reduce coupling losses for optimal light transfer between components. Reliable, reproducible processes ensure cost-effective manufacturing.
