When A is a signal of frequency υ 1 (1550 nm), input B is at frequency υ 2
(1560 nm), output is at frequency υ 2 as 1560 nm.
Figure 8c shows the input and output optical power spectrums when A is at
frequency υ 2 (1560 nm), B is at frequency υ 1 (1550 nm), output is at frequency υ 1.
Figure 8d shows the input and output optical power spectrums when A is at
frequency υ 2 (1560 nm) B is at frequency υ 2 (1560 nm), output is at υ 1 or wavelength
1550 nm. Table 3 shows the SOA parameter used in simulations [10, 11].
