Chapter 2: “Light” Propagation in Media • What is “light” has been evolving, in general EM wave propagation Entire EM spectrum is described by the Maxwell equations • Semiconductors have been used to generate “light” (semiconductor lasers and LEDs) in the wavelength range from 300nm-100 microns lasers and LEDs) in the wavelength range from 300nm 100 microns, or from deep UV to far IR. The boundaries are being pushed constantly. • The boundary between electronics and photonics is also evolving and overlapping EEE537_Fall 2010 C.Z. Ning, ECEE ASU 1
