The three-color pulses, centered at 775 nm, 864 nm and 950 nm, are obtained through second harmonic generation (SHG) of the 1550 nm pump laser and SHG of the solitons at 1728 nm and 1900 nm generated through soliton self-frequency shift (SSFS) in a large-mode-area (LMA) fiber.
The three excitation wavelengths at 775 nm, 864 nm and 950 nm, are obtained through second harmonic generation (SHG) of the 1550-nm pump laser and the 1728-nm and 1900-nm solitons generated through soliton self-frequency shift (SSFS) in a large-mode-area (LMA) fiber.
Spectral interference fringes were experimentally observed in chirped large mode area fiber Bragg grating (CFBG) in the overlapping region of the reflected spectrum of fiber modes by a high resolution spectrometer.
The equation can be solved to yield a value of approximately 330 for R S/L, indicating that for every particle in the large mode there are approximately 330 particles in the small mode.
This approach is used to predict the bend loss in large mode area holey fibers and is validated through comparison with experimental data.
Surprisingly, despite significant shear band plasticity at 77 K, failure occurs in a mixed mode manner, with large areas showing quasi-cleavage features that appear to initiate from cracks at the glass-Ti interfaces, which also limit the overall plastic strain.
A histogram of edge probabilities, p ij, shown in Figure 2, has a bimodal form which appears to distinguish between edges present in the underlying network (large mode) and edges not present in the underlying network (small mode).
The system utilizes an Er/Yb co-doped large mode area fiber in the final amplification stage.
Tag and reader placement: Referring to common display modes in a large supermarket, we deployed tags in the typical scenarios that many commodities are displayed on a shelf in line.
The reader operates at 920 925 MHz UHF band and each tag reading contains a time stamp, a tag ID, and an RSSI value which are processed by a computer running in WINDOWS 7.

In this context, subnetworks can play an important role in reducing the often very large number of elementary modes in a large network.
