refractive index of the defect will also be altered, resulting in a change in Q
v
.
However, Q
in
will be relatively unaffected; therefore, the overall Q value will be
altered and the drop efficiency will change together with the wavelength. The
difference in the overall Q value will also cause a change in the wavelength
resolution. When a heterostructure such as that in Figure 13.4 is used to vary the
structure of the overall crystal proportionally, although the operating wavelength
will change with the lattice constant, the Q value and drop efficiency, which are
dimensionless quantities, will be maintained at constant values. In other words,
multiwave ...
