2 Determine the filter transmission characteristics:
a Check center wavelength, l
FBG
, of the Fiber Bragg Grating. This
wavelength is printed on its label, for example, 1520.5 nm. This
value relates to measurements performed in a vacuum.
b Set the Optical Spectrum Analyzer:
Set the Span to 8 nm. Press Span and enter the value.
Set the center wavelength to λ
FBG
0.5 nm. Press Center and enter
the value.
Set the reference level to 0 dBm. Press [AMPL], press [Ref LVL],
and enter the value.
Set the Sensitivity to -68 dBm. Press [AMPL], press
[SENS AUTO MAN
], and enter the value.
Set the resolution bandwidth to 0.1 nm. Press [BW Swp], and enter
the value.
c Set the Tunable Laser module
Set [λ], the wavelength, to λ
FBG
1 nm, for example,
1520.5 nm 1 nm = 1519.5 nm.
Set [P], the output power, to the value in Table Table 18.
d Press the key beside the laser output to switch on the laser
output.
e Check and note the peak power level displayed by the OSA and
the wavelength at the peak power. Press Peak Search in the
Marker field.
