What is Photonics: Definition and 72 Discussions

Photonics is the physical science and application of light (photon) generation, detection, and manipulation through emission, transmission, modulation, signal processing, switching, amplification, and sensing. Though covering all light's technical applications over the whole spectrum, most photonic applications are in the range of visible and near-infrared light. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s.

    Photonics System: LED Signal Variation - Intensity vs. Amplitude

    In a photonics system where the signal from an LED is varied and picked up by an LD, can the variation of the LED signal be either the intensity of light or the amplitude of the wave? Or is this the same thing? Thanks.

    Is a Math/CS Background Suitable for Graduate Studies in Photonics?

    Hello, I have a pretty quick question. So, I am studying mathematics/computer science, double major. However, I think I want to go to graduate school for photonics. With a degree in math/cs, will this be possible to apply into a graduate photonics program? I am also minoring in physics if...

    Laser Engineering / Photonics & Alternative Energy

    I'm looking for topic ideas for my Advanced Photonics class. We have to do a 5 - 10 page research paper, considering engineering feasibility and economics, of a project that somehow uses photonics or lasers to help the alternative energy cause. However, it needs to be new and innovative, not...

    Coherent Optical Processor [Photonics]

    In my course on Microphotonics there is a brief mention of a coherent optical processor system. My problem is I don't exactly know what it's for. Basically, what is said that a transparent input image (like a photograph) is lighted monochromatically and then focussed by a lens to a spot with...

    Opinions on Photonics Engineering?

    It's a special 5 year program that's one of a kind in Canada only offered at MacMaster University. I only know that it revolves around the concept of medical technology development but I wasn't sure in detail what this field was. It sounds really good but from the look of the course load, it...
