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 …

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 …
