Mid-Infrared LEDs: 4000 nm - 5300 nm
nanoplus offers mid-infrared LEDs (MIR LED or ICLED) at any wavelength between 4000 nm and 5300 nm.
Key features of nanoplus MIR LEDs
- low power consumption
- cw operation
- broadband
- incoherent
Why choose nanoplus MIR LEDs
The growing demand for permanent monitoring of specific molecules in environmental, health, and security applications has created a need for inexpensive and power efficient light sources. We used our expertise in DFB technology and semiconductor materials to create cost-effective and highly efficient broadband light sources in the mid-infrared. nanoplus MIR LEDs display higher wall plug efficiencies and maximum output powers than previous MIR LEDs operating in continuous wave at room temperature. With their low power consumption nanoplus mid-infrared LEDs are the perfect light source for mobile gas detectors.
Quick description of nanoplus MIR LED technology
nanoplus MIR LEDs rely on the same technology as our very successful interband cascade lasers.The advantage over previous interband cascade LEDs can be attributed to stage grouping at one single antinode of the optical field and the usage of low absorbing substrates. For more insights into our technology please refer to our paper "High efficiency mid-infrared interband cascade LEDs grown on low absorbing substrates emitting >5 mW of output power" in the paper section.
