In conclusion, we have theoretically analyzed nonlinear propagation in birefringent waveguide material for the generation of coherent IR laser light by second-harmonic generation and by optical parametric oscillation. The specific guide material used in the calculation was ZnGeP2 on a GaP substrate. ...

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.
