Wavelength Electronics, Inc. was pleased to participate in the Mid-InfraRed Technologies for Health and the Environment (MIRTHE) Summer Workshop held at Princeton University. Wavelength Electronics’ poster presentation highlighted the importance of driving quantum cascade lasers with a very low noise current source.
Noise data from a typical laser diode driver was presented and compared to the noise spectrum from a purpose-built low-noise QCL driver. An approximated output spectrum, showing the impact of driver current noise, was presented based on linewidth data from cited sources.
The poster is now posted here.
Additional product information on the QCL Series is available here.
