  Multi-Wavelength Lasers sources for enhancing capacity of data centers and Networks

  In communication applications like the internet, the most simple form of optical communication is with a single fiber consisting of a single wavelength laser TX/RX scheme. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology that multiplexes a number of optical carrier signals onto a single optical fiber by using different …

  DARPA developing new material system capable of more effective high energy gamma-ray shielding

  One of biggest threat to  the deployed aerospace and defense electronics systems is radiation. Long term exposure of astronauts to radiation   is equally challenging. This force can occur naturally in space and at high altitudes on Earth, or can come in massive doses from the detonation of nuclear weapons. Deep-space and …

  Multimode propulsion provides enhanced capabilities from Warships, and UAVs to spacecraft and space missions

  

  Most spacecraft propulsion concepts can be classified into two categories: chemical and electric. Chemical propulsion relies on chemical reactions and can produce high thrust, but requires a large amount of fuel. Electric propulsion uses electromagnetic fields to accelerate ionized gases and is very fuel-efficient, but produces small amounts of thrust …

  US Military plans Battlefield Small Nuclear Reactors (SMR) for military bases and deployed troops

  

  Energy is a critical enabling component of military operations and demand for it will continue to increase over time. In particular, energy usage during contingency operations will likely increase significantly over the next few decades. The modern operational space has amplified the need for alternative energy sources to enable mobility …

  DARPA RPOD developing E-Waste recycling to address supply chain disruptions of critical elements

  Consumer electronics constitute a rapidly increasing source of waste. Cell phones, tablets and the like are typically made of non-renewable, non-biodegradable, partly environmentally toxic materials. A report from United Nations University (UNU) found that the world produced 41.8 million metric tons of e-waste in 2014 – an amount that would fill …
