hi I am your new fern photon most people are familiar with electrons and electronics similarly we photons enable a whole field called photonics the science of light Iamp;#39;m going to talk to you a little about light optical fibers and the development of optical fiber lasers photons can be portrayed as either particles or waves mathematically but for our purposes we will use a hybrid also in my presentation some technical terms will be in italics this way youamp;#39;ll know they might have external references for instance wavelength represented by the lowercase Greek symbol lambda in the optical spectrum wavelength refers to the color of light blue is a shorter wavelength around 400 nanometers and red is a longer wavelength around 700 nanometers light of course extends through a far greater spectrum than the human eye can see from x-rays through 2 terahertz radiation most optical systems operate from the UV through to the infrared optical fibers became possible with the practical un
