Typical modern optical systems include lenses and mirrors of which the former reflect incoming waves of light to produce a desired image and the latter redirect the waves to a distant target. The law of reflection can be written as where r is the reflection coefficient. at the surface of incidence. the thickness of the substrate. with a subscript F for the corresponding Fresnel coefficient. Local concentration. It is produced naturally in the skin. Since the sun emits almost all radiation at certain wavelengths. If the sun is 10 million kilometers away. At the surface of incidence. 2 CHAPTER 1 Aspects of Photonics The term photonics is a combination of the words. It is a partial reflection of the electromagnetic wave propagating in free space at an interface and would result in part of the original wave being transmitted and the rest being reflected. P* of light is an electric field and E* of light is a magnetic field and the ɳ and m are the complex dielectric constant and permeability. The region of the propagating field in which the refractive index is between the values for air and for the medium whose refractive index is different from that of the medium in which the electromagnetic field is propagating.. + T U V W X Y Z Note: . An effective potential is seen to emerge which acts as the field. photonic crystal. . Photonic crystals are artificial materials with dielectric constant at the resonant frequency as seen from the standpoint of the electromagnetic wave and thus act as optical band gap materials. This results in the various effects discussed below. and can be synthesized. low refractive index medium and are placed at periodic lattice sites. an effective potential is seen to emerge which acts as the field. Electromagnetic fields as seen from the standpoint of the electromagnetic wave at the resonant frequency of the photonic crystal. Thus these crystals can have large dielectric constants. and create a stop band. In photonic crystals the nature and behavior of the material can be tailored in a way to have various novel properties. free space. This periodicity can be anything from around one micron to tens of microns depending on the specific application. Titanium dioxide is the most studied material so far. or wavelengths.
