Internet connectivity is limited and in some cases non-existent for a significant part of the world's population. Project Loon aims to address this with a network of high-altitude balloons traveling in the stratosphere, at an altitude of approximatel

We developed a new type of optical lens device that can change its curvature like crystalline lens in human eye. The curvature changing capability of the lens allows for a tremendous tuning range in its optical power and subsequently enables miniatur

We demonstrated a tunable molding process to fabricate aspherical polymer lenses that can reduce aberrations and the total length of an optical system. Radius of curvature and conic constant are shown to be the key parameters to characterize the lens

Miniaturized imaging systems have become ubiquitous as they are found in an ever-increasing number of devices, such as cellular phones, personal digital assistants, and web cameras. Until now, the design and fabrication methodology of such systems ha

Both single and two-beam recording for two-photon monolithic multilayer optical storage are under development at Call/Recall, Inc. The depth resolution using single beam recording is less due to the intensity distribution properties of laser beam. Us

Two-photon 3D optical data storage techniques can achieve hundreds of GB data capacity per disk by storing data in multi-layer volumetric media. This approach can also provide fast data transfer rates by using parallel access techniques. It is a prom

Three-dimensional parallel readout of 2-photon multilayer optical disks can simultaneously offer high capacities (greater than 100 GB/disk) and high data transfer rates (greater than 1 Gb/s). The robust system tolerances should enable cost effective
