NOTES:
1. Operating power is set by the peak operating current I_PEAK=I_F+I_MODULATION
2. Operation at temperatures outside the specified range may result in the threshold current exceeding the
maximums defined in the electro-optical characteristic table.
3. Slope efficiency is defined as ΔPo/ΔIF at a total power output of 2 mW.
4. Rise and fall times are sensitive to drive electronics.
