Paper Abstract

Polarization-independent microlens array based on liquid crystal (PI-LCMLA) has been an interesting and important topic in optoelectronic application. In this study, a polarization-independent microlens array using double layered nematic liquid crystals (LC) with orthogonal alignment is proposed and demonstrated. Two orthogonal LC layers are separated by a double-sided indium-tin oxide silica. Further optical experiments and investigations reveals that the PILCMLA can work in polarization and polarization-insensitive mode by operating the driving voltages. The normalized focusing intensity is no polarization dependence on the incident light. Several raw images at different working modes are obtained through by utilizing this novel configuration with low applied voltages. With advantages in high optical efficiency, simple manufacture, electrically tunable focal length, low power consumption, polarization independence and multi operation modes, this device can not only be used for imaging application but also has many potential applications in optical systems.
