High-purity microwave signal generation using a low-order harmonic-suppressed rational harmonic mode-locked fiber laser incorporating a Mach-Zehnder interferometer
Abstract:phase of two paths, the IMD3 can be simultaneously enhanced by more than 10 dB for a frequency range of 510 MHz (1.98-2.49 GHz) without any change in electrical circuitry. As the linearization process that covers broad RF band would be very desirable, we measured the IMD3 for various channel bandwidths from the inset of Figure 3. As encouraging results, the IMD3 enhancements of more than 10 dB in 100 MHz channel spacing are achieved compared to free running operation. These results indicate that the proposed p… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
