“…The front end of the adaptor can be coupled to the horn antenna or, alternatively, to a coax-to-waveguide transition, with the RF test signals fed to the coaxial-cable termination. We generally use the horn antenna coupling to evaluate the ability of the modulator to withstand exposures to high-power microwave pulses [3]. We use the coax-to-waveguide transition for measurements of a bench-top microwave photonic link that includes the modulator in the RF-waveguide adaptor structure.…”

“…The width of the ridge in the RF waveguide adaptor also is 10 mm. Since the grating, whose length is between 2.7 mm and 5.4 mm, is centered in the 10 mm wide ridge, the RF electric field applied across the entire grating is quite uniform [3].…”

A compact electro-optic modulator comprising a waveguide grating formed on a small piece of lithium niobate can be integrated directly into an X-band antenna array element. A prototype link with this modulator was demonstrated.

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.
