... their simple processing. However, regular 400 nm corrugated features are required in DFB lasers. This is a very small length scale – smaller than can be conveniently made by simple photolithography – so holographic techniques are often used. Another option is to use electron beam lithography, but th ...

Abstract
... Waveguides and optical fibers operate based on the concept of total internal reflection (TIR), where light incident on a surface below a certain angle will be entirely reflected back into the waveguide rather than being transmitted in the surrounding medium. TIR is based on the difference between th ...

... the nonlinear phase as a function of the number of graphene layers and found that, at fixed power, it scales linearly with the number of layers; see Fig. 3(c). The real part of the complex nonlinear refractive index of loosely stacked graphene is found to be independent of the number of layers. Note ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
