They have concluded that the positioning of grating on the rear surface can reduce the short wavelength losses.
A wavelength dependent loss of 0.10 dB is also measured with a fluctuation of ±0.04 dB.
The influences of fiber parameters on cutoff wavelength, bending loss and effective mode area are investigated systematically.
We propose a three-layered W-type structure for laser fiber to facilitate the three-level radiative transition near 940 nm region of Nd ion, while suppressing the competing four-level transition near 1060 nm by introducing a novel highly wavelength selective loss mechanism.
Calculation of the detection range (DR) [13, 26] based on transmitter power, wavelength, path loss coefficient and a threshold for minimal received power for a communication to take place is shown below.
A shift of zero-crossing to lower wavelength indicates loss of alpha-helix content [ 24].
The technique could also be used to design planar light-wave circuits with small wavelength-dependent loss which is important for DWDM devices.
A spectral intensity calibration was performed on the three spectral bands in order to compensate for wavelength dependent losses in the detection system and the PMT sensitivity.
Departing from conventional concerns about lowering waveguide bend loss, wavelength dependence of a bending waveguide is investigated and utilized in wavelength measurement.
In the red composite, for example, blue and green light is passed along from dye molecule to dye molecule, gradually converting it to the red wavelength with as little loss as possible.
