We report experimental observation of Bardasis-Schrieffer type s-symmetry collective mode in the d-wave high T sub c superconductors.

In summary, we have reviewed the use of discrete and distributed Raman amplification for S-band transmission.

Summary form only given. Raman amplification is certain to play an ever increasing role in optical communication systems due to its remarkable versatility.

Raman amplification provides two approaches to increase the capacity of optical WDM communication that presently utilize the C- and L-bands of erbium doped fiber amplifiers.

The surface plasmon polariton-enhanced Raman spectra of size-selected, matrix-isolated C-14 neutral clusters are presented along with the calculated vibrational frequencies for the ring and linear

We present a semi-classical approach for predicting the quantum noise properties of fiber optical parametric amplifiers.

The pressure-induced phase transition in terbium vanadate and dysprosium vanadate from the zircon-type structure D sup 19 sub 4h to the scheelite-type structure C sup 6 sub 4h has been studied at r

We have utilized an iodine absorption cell to enable detailed Raman studies at low frequency (down to 15 cm sup (-1)) in a thin film of the high temperature superconductor Ba sub 2 YCu sub 3 O sub

The paper reviews recent advances of Raman fibre laser (RFL) based amplification techniques in long-haul/unrepeatered coherent transmission systems.

Stimulated Raman scattering is a nonlinear optical process that, in a broad variety of materials, enables the generation of optical gain at a frequency that is shifted from that of the incident rad
