Defense Photonics Group is using advanced fiber optic and photonic-based technologies for addressing mission critical solutions that enhance defense and security force capabilities needed to protect against modern day threats. We offer products and subsystems for command, communications and control applications within a broad range of avionic, shipboard and ground-based equipment and systems.

Optical Harness: Electrical wiring harnesses are the means for interconnecting all electrical subsystems on aircraft, ships, UAVs, etc. Since the typical harness is made of copper wires, it has a number of disadvantages relative to optical fiber: 1. Higher weight. 2. Narrower bandwidth. 3. Susceptibility to EM interference. 4. Increased loss. By replacing many signal-carrying copper wires with a single optical fiber, the resulting DPG optical harness offers a lightweight, high-bandwidth, robust and flexible alternative.

Video Distribution: Platforms carrying many data collection and sensor systems that need to be analyzed in real-time on high-resolution monitors, require a broadband network to distribute multiple video signals. DPG offers an optical network solution that provides high-bandwidth connections between multiple data collection units and multiple monitor units, leveraging mature COTS optical communication equipment.

Fiber Optic Gyro (FOG): FOG’s are critical components in navigation and guidance sub-systems, but are still too expensive for many important military applications. Using highly integrated optical circuits results in smaller and much more cost-effective devices. DPG has unique expertise in optical integration and optical materials, including an integrated ASE-based light source with performance superior to the standard SLD.

RF over Optical Fiber: Applications requiring the transmission of RF signals that are broadband or that require immunity to EMI, such as base station remoting and public safety systems, can realize huge benefits from transporting the RF signals over optical fiber. DPG is one of the world leaders in RF-on-Fiber‘ technology with expertise in broadband analog optical transmission (up to 20 GHz bandwidth). These transmission systems are also low-loss, immune to EMI and very cost-effective.
