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-x)SiO2-xHfO(2)-yErO(1.5) 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 I-4(13/2) 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).

Abstract
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-x)SiO2-xHfO(2)-yErO(1.5) 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 I-4(13/2) 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).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
