Glass Packaging: Solving Sub-Micron Alignment for Photonic HVM

The Current Bottleneck is a TCO Problem

For CTOs scaling photonic modules from R&D to high-volume manufacturing (HVM), the core issue is clear: packaging costs and yields are eroding margins. As data rates continue their relentless climb, the demand for repeatable, sub-micron alignment tolerances exceeds the capability of conventional mechanical machining and active alignment methodologies. Simply put, when the packaging becomes the bottleneck, your Total Cost of Ownership (TCO) spikes.

Glass: The Deterministic Platform for Integrated Photonics

Our upcoming live webinar directly addresses this challenge by presenting 3D laser-structured glass as the solution. Glass is no longer a passive substrate; it is the enabler of performance and scalability for photonic integrated circuits (PICs).

We leverage advanced 3D laser micromachining—specifically, femtosecond laser direct writing—to fabricate precise features directly into the bulk material. This approach bypasses the limitations of traditional CNC processing and ensures performance where it counts:

We achieve fiber-to-chip coupling and optical alignment with precision below 1 micron passively, removing the need for slow, yield-killing post-tuning steps during assembly. This shift from active to deterministic passive alignment is key to HVM.
Monolithic Reference Geometry: The structures—including V-grooves, through-glass vias (TGVs), and microfluidics—are created in a single, monolithic step. This ensures an environmentally and thermally stable reference geometry, a requirement for automation-ready packaging systems.
True Hybrid Integration: Glass facilitates robust hybrid integration of diverse functionalities: optics, mechanics, and fluidics (crucial for thermal management) within a single package, opening doors for advanced datacom and sensing applications.
New Form Factors: The inherent precision of laser glass processing allows for miniaturization and complex new form factors otherwise unreachable with traditional methods, defining the next generation of semiconductor packaging.
