A depolarization criterion in Mueller matrices
A depolarization criterion in Mueller matrices

... the matrix that describes a non-depolarizing system in several matricial representations of polarization phenomena. Fry and Kattawar [4] performed a more detailed study of these relationships in the Stokes-Mueller formalism (SMF), which included some inequalities for depolarizing systems. A system o ...

On the basis of number of modes:on the basis of number of modes of propagation the optical fiber are classified into two types: (i) Single mode fiber (SMF) and (ii) Multi-mode fiber (MMF) • Single-mode fibers – in single mode fiber only one mode can propagate through the fiber. This type of fiber h ...

Observation of modulational instability in Bose
Observation of modulational instability in Bose

... For propagation at certain negative scattering lengths it is observed that the condensate breaks up into a train of similarly sized, spatially localized clouds. These are observed to be soliton-like in that they are stable under further propagation. A single run at −1.15a0 , typical of the train for ...

Diffraction grating has periodic structure that splits and diffracts light

... Ordinary pressed CD and DVD media are every-day examples of diffraction gratings and can be used to demonstrate the effect by reflecting sunlight off them onto a white wall. (see ). This is a side effect of their manufacture, as one surface of a CD has many small pits in the plastic, arranged in a s ...

... The speed of the MMM-4Pi depends on the degree of parallelization N. The parallelization in turn depends on the available laser power. The average power of 1 to 2 mW in each 4Pi spot leads to a focal peak intensity of ~80 GW/cm2, which is lower than the ~200 GW/cm2 considered as an upper limit with ...

Harold Hopkins (physicist)

Harold Horace Hopkins FRS (1918–1994) was a renowned British physicist. His Wave Theory of Aberrations, (published by Oxford University Press 1950), is central to all modern optical design and provides the mathematical analysis which enables the use of computers to create the wealth of high quality lenses available today. In addition to his theoretical work, his many inventions are in daily use throughout the world. These include zoom lenses, coherent fibre-optics and more recently the rod-lens endoscopes which 'opened the door' to modern key-hole surgery. He was the recipient of many of the world's most prestigious awards and was twice nominated for a Nobel Prize. His citation on receiving the Rumford Medal from the Royal Society in 1984 stated: ""In recognition of his many contributions to the theory and design of optical instruments, especially of a wide variety of important new medical instruments which have made a major contribution to clinical diagnosis and surgery.""
