11.8.4 Microwave Spectrum Analyzer
Figure 11.39 gives another example of an integrated CMOS silicon photonic circuit
architecture under investigation for optical signal processing [71]. The chip modulates
an optical signal with microwave RF data, and the resulting optical spectrum is then
divided using a splitter and a set of high-performance, narrow-band optical filter banks.
The resulting filtered signal is then detected with Ge-based detectors and TIA preamps
to provide the functionality ...
