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” (semiconductorlasers and LEDs) in the wavelength range from 300nm-100 micronslasers 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 overlappingEEE537_Fall 2010 C.Z. Ning, ECEE ASU 1
