Abstract :
A stable multilayer IR optical filter is designed based on the porous silicon technology. The filter stability is achieved based on the mechanical properties of porous silicon that are used to tailor the stresses inside the multilayer structure. The filter, working at the wavelength of 1.55 ¿m, have been designed to be matched with spot sizes of 7 ¿m and 8.5 ¿m which makes it compatible with single mode fiber used in optical communications.
