The concept of modes in optics and photonics

spie.org

The shape of modes may be changed by passive optical elements (lenses, mirrors, filters), however, the number N of photons per mode cannot by increased. The energy throughput of an optical systems depends on the number of supported modes and the adaptation of the modes between the different sections of the system.

– Lenses: Chromatic aberrationbecause refractive index changes with wavelength • focal length changes with wavelength – Mirrors: Reflective losses. Lenses and inefficiencies in mirrors contribute to ~4% loss per element. • Dispersive Elements: Filters – Construction determines what fixed range of wavelengths will be allowed to pass.

Reflection and Refraction

Reflection and Refraction Physics 212 Lab . If the light is refracted as in . Figure 2, then 2 is defined as the angle of refraction. ( 1 is still the angle of incidence.) The amount that the ray of light will refract is related to the index of refraction of the medium. The index of refraction, n (no units), is defined as the ratio of the speed of light in a vacuum and the speed of light in the
