Measuring Frequency Response of High-Speed Optical Receivers Requires Microwave Measurements
Paul D. Hale, Tracy S. Clement, Dylan F. Williams
Measuring the frequency response of an optical receiver is easy if you have a standard reference receiver, a simple test setup, and a network analyzer to perform electrical mismatch corrections. Your test setup consists fo the receiver you want to test, a power meter, and a diode laser modulated by an electrical signal generator (see figure). Start by regulating the test setup with a calibrated reference receiver. Then replace the reference receiver with the receiver you wish to characterize and take another measurement. The ratio of the two measurements is almost all you need.
