Frequency Response Metrology for High-Speed Optical Receivers



Paul D. Hale, Tracy S. Clement, Dylan F. Williams


There are two types of optical sources whose modulation can be measured or calculated from fundamental principles: the hererodyne beat between two single- frequency lasers (frequency-domain) and the short pulse from a mode-locked laser (time-domain). While these sources are essential for receiver characterization, good sources are not all that is required. Aince typical optical systems must be characterized over a bandwidth as much as 10 times larger than the bit rate, calibrating the electrical instrumentation is extremely challenging. We will discuss the construction of standard optical sources and the importance of electrical calibrations in both the heterodyne and short-pulse measurement methods for receiver characterization below 50 GHz, and propose measurement strategies for going beyond 50 GHz.
