Characterization

Output power spectral density

The power spectral density of the PDX10S-5-DC-SI output was measured for different incident optical powers. Optical source is a 810 nm LED driven by a Koheron DRV110-A-375 laser driver. Power spectrum is measured using the Koheron ALPHA250 FFT analyzer.
