Abstract
The growing demand for monitoring of specific molecules has created a need for inexpensive and power-efficient light sources. In particular, the mid-infrared (MIR) wavelength range from 3 µm to 6 μm is of high interest for gas-sensing. Aiming at providing reliable broadband and cost-effective alternatives to standard optical gas analysis, nanoplus has developed light-emitting diodes (LEDs) in the MIR. The novel substrate-side-emitting devices rely on the innovative nanoplus technology for distributed feedback (DFB) interband cascade lasers (ICL) and are available at customized wavelengths between 2800 nm and 6500 nm. In this talk we will present various applications which utilize DFB ICLs or MIR LEDs and give a general overview of this technology including latest results from interband cascade photodiodes (PD) and LED-arrays in the MIR.
