Claim Text:
1. A multimode radiation source, comprising: a waveguide radiator having a first feed port for receiving a first signal having a first wavelength in a radio frequency (RF) band and for providing the first signal to the waveguide radiator so that the waveguide radiator radiates the first signal at a first location as a first spherical wave with a first phase center; waveguide feed network configured to be coupled to an RF source and that is coupled to the first feed port of the waveguide radiator, the waveguide feed network configured to receive the first signal from the RF source and to provide the first signal to the first feed port of the waveguide radiator; a hollow optical pipe having a distal end that is disposed substantially at the first location such that an emitting facet of the hollow optical pipe is substantially coincident with the first phase center, the hollow optical pipe configured to be coupled to a first optical source and configured to receive a second signal having a second wavelength in an optical band from the first optical source and to provide the second signal to the waveguide radiator so that the waveguide radiator radiates the second signal from substantially the first location as a second spherical wave with substantially the first phase center; and the hollow optical pipe further configured to be coupled to a second optical source that is configured to provide a third signal having a third wavelength in the optical band, and to provide the third signal to the waveguide radiator so that the waveguide radiator radiates the third signal from substantially the first location as a third spherical wave with substantially the first phase center.
