THE PROBLEM

Computing Infrastructure Has Reached a Physical Limit

The growth of AI is exposing the limits of today’s computing infrastructure. As electronic systems work harder, they create more heat, require more power, and become more difficult and expensive to scale, creating a critical bottleneck.

This challenge is driving interest in optical computing, where information is processed using light rather than electrons. Photonic computing may provide the breakthrough by dramatically improving speed and efficiency.

Astera is building the graphene substrate platform that enables the next generation of photonic chips and is intended to make ultrafast photonic switching commercially possible

THE SOLUTION

Building the Critical Layer Behind Photonic Computing

Photonic computing represents the next major leap in performance, and Astera provides the materials that make it possible.

Astera is building an essential component through a graphene substrate engineered to support ultrafast photonic switching to help bridge the gap between technical promise and commercial deployment.

This positions Astera at a potentially valuable point in the value chain. Instead of competing at the crowded application level, the company is focused on the foundational material layer that could help enable the entire market.

ASTERA’S TECHNOLOGY

MW-PECVD: Rapid Graphene Growth for Photonic Applications

Astera’s technology is built around a streamlined manufacturing pathway designed to produce photonic-grade graphene with the speed, quality, and scalability needed for real commercial use.

By enabling rapid graphene growth, the process creates a faster path from raw carbon input to a high-performance graphene substrate suitable for photonic applications.

Feedstock Intake

Waste plastics and other carbon inputs are converted into usable source material, creating a scalable starting point for graphene production.

Flash Joule Graphitization

The carbon material is rapidly refined into high-purity graphitic material, forming the quality base needed for advanced photonic applications.

MW-PECVD Deposition

Graphene is grown directly on an engineered substrate, producing a cleaner and more stable semiconductor substrate by avoiding transfer-related defects.

Defect Healing

The material is further refined into photonic-grade monolayer graphene engineered for faster switching, better thermal performance, and greater commercial reliability.

Designed for Real-World Scale

Breakthrough technologies only matter if they can be produced consistently and at scale. Astera’s approach is built around manufacturability, with a focus on speed, repeatability, and integration into existing production environments.
