Nonlinear interference noise (NLIN) is arguably the most important factor limiting the capacity of fiber-optic communication systems. It is customary to classify nonlinear phenomena as either intra-channel, or inter-channel. Intra-channel effects relate to the nonlinear distortions undergone by each.....

Laser frequency can be converted very efficiently nowadays using electrically field poled ferroelectric crystals, such as LiNbO3 or KTiOPO4. Unfortunately, these crystals are readily available only with relatively small aperture – up to 1 mm in the critical Z axis of the crystal – thereby severely l.....

Most ultrasound imaging systems use multiple transducer elements to transmit and receive acoustic pulses. Beamforming of the signals detected by the individual elements of the array increase the signal-to-noise ratio and angular resolution, while performance in the digital domain, implies that the a.....

Textiles that have been modified by integrating peptide nanostructures show remarkable properties. These include the physical and chemical properties of the fabric, such as strength and fire-resistance, as well as much more advanced properties including enzymatic activities such as self-cleaning an.....
