Modular Optical Aperture Building Blocks (MOABB)

Dr. Gordon Keeler

Free-space optics today requires a telescope, bulk lasers with mechanical beam-steering, detectors, and electronics. The Modular Optical Aperture Building Blocks (MOABB) program seeks to design all of these components into a single integrated device. In what would be deemed as the most complex electronic-photonic circuit ever fashioned, the program’s performers will work to create a wafer-scale system that is 100x smaller and lighter than conventional systems and can steer the optical beam 1,000x faster than mechanical components.

A primary goal of the MOABB program is the demonstration of integrated electronic-photonic unit cells that can be tiled together to form large-scale planar apertures. The program calls for devices that are modular and scalable to apertures of up to 10 centimeters in diameter and that can run at 100 watts of optical power. Another primary objective is the operation of a fully-functional, chip-scale LIDAR system capable of three-dimensional (3-D) imaging at a range of 100 meters.

Successful completion of the MOABB program could enable rapid 3-D scanning using devices smaller than a cell-phone camera, high-speed laser communications without mechanical steering, foliage-penetrating perimeter sensing, remote wind sensing, and long-range 3-D mapping. Such capabilities could, in turn, find applications in intelligence, surveillance, and reconnaissance (ISR), autonomous navigation, optical communication systems, and robotics.

Selected DARPA Achievements

DARPA collaborated with industry on stealth technology.
DARPA’s Stealth Revolution
In the early days of DARPA’s work on stealth technology, Have Blue, a prototype of what would become the F-117A, first flew successfully in 1977. The success of the F-117A program marked the beginning of the stealth revolution, which has had enormous benefits for national security.
DARPA microelectronics gave rise to today's GPS devices.
Navigation in the Palm of Your Hand
Early GPS receivers were bulky, heavy devices. In 1983, DARPA set out to miniaturize them, leading to a much broader adoption of GPS capability.
First rough conceptual design of the ARPANET.
Paving the Way to the Modern Internet
ARPA research played a central role in launching the Information Revolution. The agency developed and furthered much of the conceptual basis for the ARPANET—prototypical communications network launched nearly half a century ago—and invented the digital protocols that gave birth to the Internet.
