Notes:
1. Operating power is set by the peak operating current IPEAK=IBIAS+IMODULATION.
2. Operation at temperatures outside the specified range may result in the threshold current
exceeding the maximums defined in the electro-optical characteristics table.
3. Slope efficiency is defined as ∆Po/∆IF at a total power output of 1.3 mW.
4. Rise and fall times are sensitive to drive electronics, 200ps rise and fall times are achievable
with Honeywell VCSELs.

5. Beam divergence is defined as the total included angle between the 1/e intensity points.
