Direct modulation of photonic crystal vertical-cavity surface-emitting lasers (PC-VCSELs)‎

الملخص EN

The occurrence of various laser outputs from photonic-crystal vertical-cavity surfaceemitting lasers (PC-VCSELs) was investigated ranging from the usual output obtained from such devices, periodic, multi-periodic, aperiodic and chaotic one as a result of the modulation of injection current.

The study proved that PC-VCSEL dynamics is strongly affected by the variation injection current signals and exhibits dramatic changes in the laser output.
