Vertical-cavity surface-emitting laser characterizations for space applications

摘要

In this paper, we study the critical parameters of 1550 nm vertical-cavity surface-emitting lasers (VCSEL) for several applications in space environment like satellite (telecommunications and observation) and deep space (probes and rover). The analysis is focus in the main parameters degrading the VCSEL behavior in wide application field. These parameters are the optical output power, the threshold current and the relative noise intensity (RIN) according to the temperature that affects the storage and mostly the operation of the laser diode. Characterization processes and results are presented here.
