BATOP GmbH is a privately held company founded in 2003, focused on growth of semiconductor nonlinear optical devices like saturable absorbers (SAM - saturable absorber mirror, SOC - saturable output coupler) for lasers, saturable noise suppressor (SANOS) for improvement of optical signals, and photoconductive antennas (PCA) for THz generation and detection.
We grow thin film stacks of the materials GaAs/AlAs/InAs on GaAs wafers for optoelectronic devices, make wafer processing, device packaging and testing.
