The Case for SWIR VCSELs in Next-Generation Consumer Sensing
A comprehensive analysis of why short-wave infrared (SWIR) VCSELs outperform near-infrared (NIR) alternatives for 3D sensing, AR/VR, and LiDAR; covers SNR headroom, eye safety, range extension, and the role of InPHRED's nanoporous DBR in making SWIR VCSELs manufacturable at commercial scale.

Visible GaN RC-LED for Wearable Health Sensing
How InPHRED's blue/green RC-LED improves health metric accuracy versus conventional broadband LEDs with improved spectral selectivity, better skin-tone independence, and access to new biomarkers.
Nanoporous InP DBR: Physics, Fabrication, and Performance
An introduction to the electrochemical porosification process — how selective anodization of n⁺-InP creates a homoepitaxial Bragg reflector with tunable refractive-index contrast exceeding AlGaAs/GaAs.
Non-Invasive Optical Glucose Monitoring with SWIR Photonics
How SWIR wavelengths penetrate skin and adipose tissue to isolate blood glucose signal — combining multiple SWIR and NIR wavelengths to address the accuracy limitations of prior NIR-only attempts.
RC-LEDs for Ultra-Short-Reach Optical Interconnects
Resonant-cavity LEDs as a low-power, high-bandwidth alternative to VCSELs and copper for die-to-die and chiplet integration — benchmarking bandwidth density and power consumption at <1 pJ/bit.
SWIR LiDAR for All-Environment Automotive ADAS
Why SWIR wavelengths outperform visible and NIR LiDAR for long-range highway ADAS: eye safety at high power, reduced solar background interference, and superior performance in rain, fog, and dust.
