We propose the control of the radiation of an optical leaky wave antenna through optical pumping schemes. A bi-directional pumping is eventually adopted, and the tunability of the radiation is observed
CMOS compatible leaky wave optical antennas are proposed and analyzed for electronically controlled radiation pattern generation. Very directive far field radiation pattern (>15dB) is generated from a Si3N4 leaky wave antenna with silicon periodic perturbations.
We report real-time imaging and dynamics monitoring of micrometer predefined and random sized particles by time–space-wavelength mapping technology using a single-detector. Experimentally, we demonstrate real-time line imaging of a 5μm polystyrene microsphere, glass powder particles and patterns such as fingerprints with up to 5μm resolution at 1 line/50ns capture rate. By using the same setup, real-time...
We propose and demonstrate single detector real-time line imaging with up to 1 mum resolution at 1 line/50ns capture rate. Experimentally we demonstrate real time line imaging of <25 mum particles and patterns such as fingerprints.
