THIS PROPOSAL DESCRIBES AN APA OPTICS PROGRAM TO DEVELOP A HIGH SPEED (100GHZ) GAAS WAVEGUIDE BASED MACH ZEHNDER MODULATOR. OUR APPROACH CENTERS ON THE USE OF A BURIED ELECTRODE CONFIGURATION TO ACHIEVE VELOCITY MATCHING OF THE RF AND OPTICAL SIGNALS. THIS WE FEEL WILL RESULT IN A DEVICE WITH A BROADBAND RESPONSE FROM DC TO 100GHZ. WE WILL WORK IN CONJUNCTION WITH THE ULTRFAST SCIENCE LAB AT THE U ...

Grinding is used to satisfy figure and finish requirements for optics, removing successive layers of material to ensure alleviation of any damage created from the prior operation. Consequently, fabrication times are slow and expensive. The optics manufacturing industry currently lacks physics-based models needed to understand the impact of process and material variables on final part quality and ...

"Noisy enclosures present a problem of great importance to the Army's Command and Control Operations On-the-Move for Future Combat Systems. Examples of these noisy enclosures are Command and Control communications shelters and Vehicles. Fully equippedcommunication shelters are extremely noisy. A unique and effective solution to the noise problem in both fixed and mobile shelters is offered. The ...

This Phase I SBIR Project will develop an Advanced Unbalance Control (AUC) system based on active magnetic bearing (AMB) technology and advanced feedforward control algorithms. The AUC system will offer at least an order of magnitude increase in bothresponse speed and unbalance response reduction as compared to the best available mechanical unbalance cancellation methods. This will be accomplish ...

A motif is a non-commonplace, specific narrative element (such as a striking event, character, or object) that is repeated across stories found within the same cultural group, and concisely expresses complex cultural and political ideas through the inferences it evokes about a particular situation. If we can track motifs in communications, we will have a significant advantage in modeling informati ...

Over the past decade there has been a rapid growth of wireless communication technology. As a result, portable computing devices such as notebook computers and personal digital assistants have begun to take advantage of wireless technology, thus providingincreasing access to wireline multimedia applications for mobile users. For multimedia applications to be supported successfully in wireless netw ...

ABSTRACT: Secure and efficient IP multicast improves efficiency of bandwidth utilization in tactical networks such as the Airborne Networks and facilitates effective and timely dissemination of mission critical information among tactical edge users. In this SBIR effort, Architecture Technology Corporation (ATC) proposes an innovative Adaptive and Integrated Multicast for the Airborne Networks (AI ...

ABSTRACT: The Air Force has identified the need for a technological capability to provide secure, dynamic and efficient multicast services over crypto-partitioned heterogeneous tactical networks, to ensure efficient use of bandwidth-constrained airborne networks. During Phase I of this SBIR, Architecture Technology Corporation (ATC) defined an innovative technology called Adaptive and Integrated ...

The Navy's C4I systems of tomorrow will contain networked multimedia applications to support functions used by decision makers and war fighters. A number of challenging problems must be addressed before such networked multimedia applications can be implemented in a cost-effective fashion. One of these challenges is the delivery of audio and full-motion video over a heterogeneous, enterprise- ...
