Infrared emitter technology continues to evolve. Trends include the development of devices with even faster rise/fall times for higher data rate communication (e.g., for Li-Fi or advanced optical sensing). There is also a push for higher wall-plug efficiency (more light output per electrical watt input) to reduce power consumption in battery-operated devices. Integration is another trend, with emitters being combined with drivers, modulators, or even detectors into single modules or ICs to simplify system design. Furthermore, emitters at different wavelengths (e.g., 940nm, which is less visible to some CMOS image sensors, or 850nm for surveillance cameras) are being optimized for specific application ecosystems.
