    hello everybody ,
    I looked some link. according me , optical integrated circuit is circuit in which optical and electronics component connected together to provide long distance light transmission

    optical fiber - light can propagate throw optical fiber

    what is difference between waveguide and optical fiber. both are component or device circuit ?

    Hello,

    An optical integrated circuit can also be an optocoupler.
    There will be no light coming out of the device, but it will provide isolation between circuits.

    A waveguide is most times a steel or copper pipe to transport microwaves.

    Here is a page of the EDUCYPEDIA about opto electronics:

    If A waveguide transport microwaves. than what is work of fiber optics?. what is difference between waveguide and optical fiber. both are component or device circuit ?

    Optical fiber is used to transport IR and visible signals. It has properties which are superior free space.

    Except in the case of an opto slot detector.;)

    An optical fiber can be classified as an optical waveguide although it operates somewhat differently from a metal microwave waveguide.

    A metal waveguide, such as used at microwave frequencies, can't be used at optical frequencies due to the difference in wavelength. A metal waveguide needs to have internal dimensions comparable to the wavelength of the signal (in the cm region for microwaves). That's doable at microwave frequencies but not possible at the short wavelengths of optical signals (around 1 μm or less).
