For example, a resistance value of 10 ohms and a corresponding emitted optical power of 2dBm is input into Pda = a x + b, resulting in 10=2 a + b; inputting the resistance value of 20 ohms and the corresponding 3dBm emitted light power Pda = a x + b to obtain 20=3a + b; the constant a =10 and the constant b = -10 are obtained from 10=2 × a + b and 20=3a + b, that is, the trained optical power model is Pda =10 x-10.

Specifically, in this embodiment, two sets of resistance values and emission currents are input into a model Ida = m × z + n for calculation, so as to obtain a trained optical power model, where z is the laser emission current, Ida is the laser resistance value, and m and n are constants. For example, a resistance value of 10 ohms and a corresponding value of 1mA emission current are input into Ida = m × z + n, resulting in 10= m + n; inputting the resistance value of 10 ohms and the corresponding value of the 2mA emission current into Ida = m + z + n to obtain 20=2 + m + n; from 10= m + n and 20=2 × m + n, m =10, n =0 is obtained, i.e. the trained emission current model is Ida =10 z.

That is, when the resistance value of the laser is 10 ohms, the emitted light power is 2 dBm; when the resistance value of the laser is 20 ohms, the emitted light power is 3 dBm; when the resistance value of the laser is 30 ohms, the emitted light power is 4 dBm; when the resistance value of the laser is 40 ohms, the emitted light power is 5 dBm; when the resistance value of the laser was 50 ohms, the emitted optical power was 6 dBm.
