Report on “Optical Computing: Need and Challenge” An optical computer is a device which performs all the computations performed inside the computer using optical fibers, photons, thin films etc. instead of using thing electrical wires, electrons, and transistors. The reviewed paper talks about the need for optical computing, its advantages over current computational systems, how an optical switching circuit functions, and the challenges faced by optical computing in the current generation and how long before the advent of a prototype optical computer. The first point the authors make in their paper is the need for optics in computing. The reliability of optical components like Lasers, and optical fibers have been proven and are used in a multitude of devices like Laser printers, disk drives, photocopiers and scanners, projectors etc. According to the authors, optical computing has an edge over regular electronic components. Some of the advantages among many include immunity for Electromagnetic interference (EMI) and short circuits, ability for different photons to travel in a single fiber without cross talk, large

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
