In the healthcare segment, wafer specifications diverge between diagnostics platforms-where high-speed electro-optic switching enables real-time biosensing-and imaging systems that leverage nonlinear photonic effects for high-resolution tomography.

Microwave photonics introduces another layer of complexity, as radar subsystems and signal-processing modules require wafers with consistent electro-mechanical properties to maintain phase stability under high-frequency operation. Meanwhile, quantum photonics applications bifurcate into substrates optimized for quantum computing interconnects, which emphasize ultra-low loss waveguides and crystalline uniformity, versus quantum sensing instruments that harness the material’s nonlinear coefficients for entangled photon generation. Similarly, optical modulators and pressure sensors within the sensors and actuators domain necessitate precise control over film thickness, while telecommunications use cases span five-inch wafers for 5G infrastructure as well as larger formats for fiber-optic and satellite communications.

This complexity extends further when factoring end-use industries. Aerospace and defense platforms seek wafers capable of enduring extreme environmental stresses in communication and radar systems, whereas consumer electronics applications demand cost-effective consumer optics and wearable form factors.
