Abstract

The vertical cavity surface emitting laser (VCSEL) characteristics of voltage change in the integrated VCSEL microprobe head have been analyzed using the finite difference time domain (FDTD) method and laser rate equations. The reflectance difference of 9.7% from the phase change media was calculated with the GaP microprobe having a 150 nm aperture, resulting in the voltage change of 2.9 mV in the VCSEL. The 30 dB CNR of the readout signal was evaluated with the relative noise of VCSEL and it was found that the CNR could increase with further improvement of the VCSEL structure and the reflectance difference in the media.
