Wavelength Conversion Module

Technology: Laser diodes
Partner: NEL / NTT Electronics

NEL’s periodically poled lithium niobate (PPLN) waveguide modules convert light to the visible, near-infrared, and mid-infrared. The module consists of a PPLN waveguide, a thermoelectric cooler, and a thermistor. Custom design of the poling periodicity is possible upon definition of pump and signal wavelengths.
