Integration of erbium-dooped lithium niobate microtubes into ordered macroporous silicon

摘要

Er3+-doped LiNbO3 microtubes have been prepared by the infiltration of ordered macroporous silicon with Er:LiNbO3 melts (see Figure). The microtubes consist of single-crystalline segments and exhibit the characteristic photoluminescence of Er3+, which coincides with the transmittance maximum of silica-based optical components.
