The earliest use of light as signal or in communication can be traced to use of mirrors, fire beacons, and smoke signals. This presentation will highlight and describe major milestones leading up to 12th century that contributed to the evolution of both geometrical and physical optics and how this affected our current understanding of astronomy, coherence, and signal transmission. The major players behind this maturation of photonics, who had lived and worked in areas that now lies in Bangladesh, China, Egypt, Greece, India, Iraq, Iran, Spain, and Syria, will be discussed along with their works and discoveries in chronological order. The speaker will show that this process, that relied once only on philosophical discourses culminated in both experimentation and analysis, was a function of concurrent evolution of number systems, algebra, and analytical geometry.
