17 Apr 2014 ID Quantique's ID350 series consists of a packaged Periodically Poled Lithium Niobate (PPLN) crystal designed to generate photon pairs at telecom wavelengths using spontaneous parametric down-conversion (SPDC), where a single photon at 775nm generates a pair of photons at 1550nm. It can also be used for Second Harmonic Generation (SHG) or Sum Frequency Generation (SFG). The crystal comes fiber-coupled to provide minimal insertion losses. It contains an internal temperature controller able to adjust wavelength through a USB connection and GUI software (Labview VI also delivered).
APPLICATIONS
- Spontaneous down-conversion
