We demonstrate a novel optical probing technique using the reflection-induced change in voltage of a GaAs vertical cavity surface emitting laser (VCSEL). We present the modeling and experiment of the VCSEL based probing. A two-dimensional image probing is successfully demonstrated.

Key words: VCSEL, reflection, voltage change, optical storage, contact head
