The correct answer is: A. Christian Huygens.
Christian Huygens was a Dutch physicist, mathematician, astronomer, inventor, and horologist. He is best known for his work on light and optics, including his wave theory of light. Huygens proposed the idea of transmission of light via dielectric waveguide structure in his 1678 book Treatise on Light.
Karpon and Bockham are two scientists who worked on the development of dielectric waveguides in the 1960s. Hondros and debye are two scientists who worked on the development of dielectric waveguides in the 1970s. Albert Einstein is a famous physicist who is best known for his work on relativity. He did not work on the development of dielectric waveguides.
Dielectric waveguides are structures that guide light by confining it to a region of space. They are used in a variety of applications, including optical fibers, lasers, and integrated optics.
