Abstract

The functionality of optical components relies heavily on the composition-dependent properties of germanosilicate materials, which include the refractive index, photosensitivity, and microstructural properties. Recent studies and parallel developments are presented of germanosilicate films with composition x of Ge content (i.e., x GeO 2 : ( 1 x ) SiO 2 ) that were synthesized by the solgel process for various integrated photonic applications undertaken. The following novel aspects are discussed with respect to the effect of composition of the glassy films ( 0.05 x 0.40 ) : determination of spectral optical properties, UV imprinting of optical waveguides with relatively large index change ( Δ n ) , and quantum-well intermixing enhancement observed in InGaAs ( P ) / InP quantum-well optical devices. The implications of the results are discussed.
