Our R&D philosophy is simple: Develop and commercialise products that directly solve our customers’ application challenges.

This application-driven approach ensures that each product we design becomes a strategic differentiator within our customers’ systems. Our engineers work side by side with OEM partners from concept through qualification, applying concurrent engineering to optimise performance, manufacturability, and cost. Whether your need is a customized variation of a standard product or a fully dedicated subsystem, G&H’s multi-disciplinary engineering team delivers solutions that perform - technically, commercially, and operationally.

A core strength of G&H lies in our vertically integrated capability - from crystal growth, coating, and optical fabrication to electronic integration and precision assembly. This integration allows us to develop both custom photonic components and fully engineered subsystems, ensuring optimal system performance and lifecycle control.

We treat every system as more than a collection of parts. By engineering interconnected, application-specific components within a unified design framework, we achieve the technical edge our customers need to differentiate their platforms in the market. This close interaction between system engineers and component specialists is made possible by our globally integrated R&D organization, ensuring knowledge transfer and consistent quality across sites.

G&H’s development process is structured, agile, and globally harmonized. Our AS9100-compliant New Product Development (NPD) framework ensures every product is designed, validated, and transferred to manufacture with discipline and traceability.

Our process includes:

• Defined phase gates to control progress and ensure cross-functional alignment.
• Regular risk and compliance reviews to meet regulatory and market-driven requirements.
• Design for Manufacture (DFM) integration early in the lifecycle.
• Customer collaboration and adaptation to external or government-defined formats.
• Comprehensive project management using formal quality, documentation, and reporting systems.

This disciplined approach ensures that every product developed by G&H is competitively positioned, technically validated, and ready for scalable production.

With decades of experience across diverse photonic disciplines, our engineers know what works - and where innovation can break new ground. As photonics technology continues to expand into new applications, G&H’s R&D teams draw on this experience to identify and solve emerging failure mechanisms, ensuring performance, reliability, and longevity in demanding environments.

At G&H, performance and cost efficiency are developed in parallel. As a high-volume commercial supplier, we design products not just for technical excellence, but for long-term competitiveness.

Our cost optimization strategy includes:

• Defining target cost structures from the outset of each project.
• Implementing continuous cost-reduction plans across the lifecycle.
• Leveraging our vertically integrated manufacturing network to maximise internal content.
• Coordinating with our global supply chain and production engineering teams to improve yield and reduce waste.

This approach ensures that every product meets market expectations for both performance and affordability - without compromising quality or reliability.

From concept and prototype through qualification and series production, G&H delivers end-to-end photonics product development that combines technical depth, system-level insight, and manufacturing excellence. Partner with G&H to co-develop your next generation of photonic products and subsystems.
