Abstract: A method includes applying a stress to a polymer thin film to stretch the polymer thin film along a first in-plane direction, and subsequently applying a stress to the polymer thin film to stretch the polymer thin film along a second in-plane direction orthogonal to the first in-plane direction to form an ultra-high modulus polymer thin film. Calendaring or hot pressing of the ultra-high modulus polymer thin film may improve its optical and/or thermal properties.

Abstract: A high voltage-driven system includes a high voltage optical transformer and a high voltage driven device, where the high voltage optical transformer is located in close proximity to the high voltage driven device. A high voltage connection between the high voltage optical transformer and the high voltage driven device may be shorter than a low voltage connection between the high voltage optical transformer and a low voltage power source used to control the transformer.

Abstract: An optical device includes a first polarization selective reflector positioned relative to a spatial light modulator; and a first reflective assembly positioned relative to the first polarization selective reflector so that the first polarization selective reflector receives first light from the spatial light modulator and directs at least a portion of the first light having a first polarization toward the first reflective assembly as second light. The first reflective assembly receives the second light from the first polarization selective reflector and directs at least a portion of the second light toward the first polarization selective reflector as third light having a second polarization. The second polarization is distinct from the first polarization.

Abstract: A mechanically and piezoelectrically anisotropic polymer thin film is formed from a crystallizable polymer and an additive configured to interact with the polymer to facilitate chain alignment and, in some examples, create a higher crystalline content within the polymer thin film. The polymer thin film and its method of manufacture may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 5% of the molecular weight of the crystallizable polymer. Example polymers may include vinylidene fluoride, trifluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, and vinyl fluoride. Example additives may occupy up to approximately 60 wt. % of the polymer thin film. The polymer thin film may be characterized by a piezoelectric coefficient (d31) of at least approximately 5 pC/N or an electromechanical coupling factor (k31) of at least approximately 0.1.

Abstract: A liquid lens architecture includes a transparent substrate, a multilayer thermoplastic polyurethane (TPU)-based membrane overlying at least a portion of the transparent substrate, and a liquid layer disposed between and abutting the transparent substrate and the multilayer thermoplastic polyurethane-based membrane. The TPU-based membrane may exhibit a reversible elastic response to imposed strains of up to approximately 2% and is configured to limit the transpiration of fluid to less than approximately 10−2 g/m2/day.
