摘要： A photovoltaic device includes a photovoltaic layer configured to convert light into electrical power, a distributed Bragg reflector (DBR) layer having one to three periods disposed adjacent the photovoltaic layer, a metal layer, disposed adjacent the DBR layer, configured to reflect light passed through the photovoltaic layer to the DBR layer, and a phase matching layer disposed between the metal layer and the DBR layer, the phase matching layer configured to match a phase between the DBR layer and the metal layer over a selected wavelength band. The metal layer has a non-uniformed textured surface facing the phase matching layer. The photovoltaic device further includes an anti-reflection coating layer disposed on a top surface of the photovoltaic layer, and a substrate on which the metal layer is disposed. The substrate may be textured on a surface facing the metal layer.

摘要： Electro-optic modulators are disclosed. An electro-optic modulator comprises an electro-optic polymer layer, semiconductor layers, ferroelectric material layers, and electrodes. The semiconductor layers are positioned on each surface of the electro-optic polymer layer. The refractive index of the semiconductor layers in the optical and RF domains is higher than the refractive index of the electro-optic polymer layer in the optical and RF domains. The ferroelectric material layers are positioned on each semiconductor layer opposite the electro-optic polymer layer. The refractive index of the ferroelectric material layers in the RF domain is higher than the refractive indices of both the electro-optic polymer layer and the semiconductor layers in the RF domain. The refractive index of the ferroelectric material layers in the optical domain is lower than the refractive index of the semiconductor layer in the optical domain. The electrodes are positioned on each ferroelectric material layer opposite the semiconductor layer.

摘要： Described herein are electromagnetic traps or tweezers. Desired results are achieved by combining two recently developed techniques, 3D negative refraction flat lenses (3DNRFLs) and optical tweezers. The very unique advantages of using 3DNRFLs for electromagnetic traps have been demonstrated. Super-resolution and short focal distance of the flat lens result in a highly focused and strongly convergent beam, which is a key requirement for a stable and accurate electromagnetic trap. The translation symmetry of 3DNRFL provides translation-invariance for imaging, which allows an electromagnetic trap to be translated without moving the lens, and permits a trap array by using multiple sources with a single lens.

摘要： According to embodiments of the invention, the design and fabrication of a binary superimposed grating (BSG) results in better performing devices that may be fabricated using existing technology. The fabrication process includes forming grating features based upon repeating features of the desired superposition function. The design process also relaxes the processing requirement for equivalently performing devices.
