± 1 nm, check and note the power level displayed by the
OSA at every 0.1 nm interval. That is, fill out the table shown in
Table Table 19.
3 Determine minimum value of filter transmission and actual Fiber-
Bragg-Grating center wavelength, λ
0
.
a Check for minimum transmitted peak power in Table Table 19.
b Mark the associated wavelength set on the Tunable Laser,
TLS_l
0
, and note the value in the test record.
