Abstract
A VCSEL chip of 250 µm by 250 µm is placed inside a liquid crystal cell with a gap between the emitting area and the upper glass plate of about 30 µm. This allows covering the VCSEL with a thin layer of liquid crystal after filling the cell through capillary forces. The light emitting properties are investigated, including the optical power, divergence and polarization, all in function of the applied current to the VCSEL. It is observed that the polarization states of the laser beam can be changed by using different type of liquid crystal. This technology opens an effective way to fabricate integrated VCSEL chips in optoelectronic devices and different experiments are planned in the future with the fabricated devices.
