1. an optical wavelength light-dividing device, comprises:

  • One first substrate;

    One input block, is to be formed on this first substrate, and has a slit, to receive an optical signal;

    One grating, is to be formed on this first substrate, can produce one of output the first light beam according to this optical signal;

    One first optical reflection unit, is to be formed on this first substrate, comes from this first light beam of this grating to reflect output;

    AndOne second substrate is to be covered on this input block and this grating;

    Wherein, this input block, this grating and this first optical reflection unit system utilize a high-energy light source to form the photoresist layer institute that expose, and the wavelength coverage of this high-energy light source between be 0.01 how rice to 100 how meter between.
