InPHRED was founded to solve a 30-year photonics challenge and bring the resulting technology to market across three high-growth applications.
The photonics industry has long been constrained by a fundamental limitation: the physical properties of InP and GaN materials make it nearly impossible to build homoepitaxial DBR mirrors with sufficient reflectivity for VCSELs and RC-LEDs.
InPHRED's founders, led by Yale Professor Jung Han, discovered that selective electrochemical etching of n⁺-doped semiconductor layers creates a nanoporous structure with precisely tunable refractive index, delivering the mirror contrast needed for lasing in a scalable process.
From this single platform, we are building manufacturable light sources across previously inaccessible wavelengths for consumer sensing, digital health, and next-generation data center optical interconnects.
Our team brings together world-class photonics science, semiconductor industry operations, and go-to-market strategy.
Since 2023, we have proven our core technology, transferred our manufacturing to foundries, and established revenue.
Our fabless design house business model enables commercial-scale production without vertical integration.
