چکیده انگلیسی
This paper deals with glass-based photonic structures, used to control and modify the optical and spectroscopic properties of rare earth ions. The spectroscopic assessment of sol-gel-derived planar waveguides and 1D photonic band gap structures is reported. The spectroscopic, optical, and structural properties of planar waveguides with (100 â x)SiO2-xHfO2-yErO1.5 with y = 0.3, 0.01; and x = 10, 20, 30, 40 have been investigated by photoluminescence and Raman spectroscopy. The radiative quantum efficiency of the 4I13/2 metastable state of Er3+ ions is between 84 and 88% depending on the Si/Hf molar ratio. The sol-gel-derived one-dimensional cavity was realized by a Eu3+-activated dielectric layer placed between distributed Bragg reflectors (DBRs).
