Direct Antenna Modulation for High-Order Phase Shift Keying [PDF]
An antenna capable of directly phase modulating a radio frequency carrier is discussed, designed, and measured as both an antenna and a modulator. Access point densification for the Internet of Things will be expensive in part due to the cost and inefficiency of amplifying waveforms with large peak-to-average power ratios for downlink transmission ...

Realization of an all-optical zero to π cross-phase modulation jump [PDF]
We report on the experimental demonstration of an all-optical π cross-phase modulation jump. By performing a preselection, an optically induced unitary transformation, and then a postselection on the polarization degree of freedom, the phase of the ...

Degradation of modulation and noise characteristics of semiconductor lasers after propagation in optical fiber due to a phase-shift induced by stimulated Brillouin scattering [PDF]
Here we demonstrate theoretically that stimulated Brillouin scattering (SBS) can induce a phase shift of the optical carrier relative to its sidebands due to the waveguiding effect of the optical fiber on the acoustic wave.

Quantum key distribution based on a Sagnac loop interferometer and polarization-insensitive phase modulators [PDF]
We present a design for a quantum key distribution(QKD) system in a Sagnac loop configuration, employing a novel phase modulation scheme based on frequency shift, and demonstrate stable BB84 QKD operation with high interference visibility and low quantum
