A 7-8 GHz Serrodyne Modulator in SiGe for MIMO Signal Generation [PDF]
An 8-bit 360o sawtooth modulated phase shifter is used to apply very small frequency offsets to RF signals between 7 and 8 GHz. Offsets between 6 Hz and 10MHz can be obtained. Such frequency offsets can be used to generate orthogonal signals, which are required in e.g. MIMO applications. Each undesired frequency component is suppressed to below -30 dBc.

Time‐varying optical vortices enabled by time‐modulated metasurfaces
Abstract In this paper, generation of optical vortices with time‐varying orbital angular momentum (OAM) and topological charge is theoretically demonstrated based on time‐modulated metasurfaces with a linearly azimuthal frequency gradient. The topological charge of such dynamic structured light beams is shown to continuously and periodically change ...

Realization of fiber-based laser Doppler vibrometer with serrodyne frequency shifting [PDF]
We demonstrate a laser Doppler vibrometer (LDV) based on the serrodyne frequency shifting technique. A proof-of-principle system is implemented on the basis of fiber-optic components but opens the way toward an ultracompact integrated LDV system on a ...
