An integration method of grating array with different periods and Fabry-Perot (FP) resonator with an all-dielectric single- cavity is proposed. It is based on the capacity of spatial separation of spectral component by the grating and band-pass characteri
The broadband photochromic effect on undoped and rare-earth-doped lead lanthanum zirconate titanate (PLZT) ceramics was studied under the illumination of ultraviolet light at 360 nm. The photocarriers’ trapping and detrapping processes of thermal disconne
