Abstract
The present disclosure provides a dispersive optical device (DOD) that includes a first material having a first refractive index (n1) at a first wavelength (W1) and a first chromatic dispersion (D1); and at least one dispersive optical element (DOE) optically coupled in the first material, the at least one DOE comprising a second material containing a chromophore. The at least one DOE has a second refractive index (n2) at W1; a ratio of n2 to n1 is less than or equal to about 1.05; and the at least one DOE has a second chromatic dispersion (D2), wherein D2 is at least 10 times greater than D1.
