Nonlinear optics is a part of optics, dealing with various kinds of optical nonlinearities e.g. in nonlinear crystal materials (including both dielectrics and semiconductors) or in optical fibers and other waveguide devices. Nonlinear effects with light are those where e.g. twice the optical input intensities does not simply result in …

Switches are important components of any communications network. Switches are found inside network-connected devices and used to change data transmission paths when transmitting data between devices. By quickly changing the transmission pathway and sending data only to relevant devices, the total load on the network can be reduced.   Optical …

The U.S. Department of Defense (DoD) maintains installations worldwide; worth over $1.2 trillion and critical to U.S. national security. Physical changes to the environment such as flooding, drought, and extreme storms disrupt U.S. military capabilities and facilities, including training ranges, bases, and housing. A 2019 DoD assessment found that out …
