Application

Germanium(IV) oxide can be used:

To prepare glasses for nuclear radiation shielding and ultra-broadband amplification. For example, germanium and bismuth oxide glasses.
As a precursor to synthesize GeO₂/TiO₂ nanocomposites that can be used for the photocatalysis of organic pollutants.
As an anode material for lithium-ion batteries due to its high lithium storage capacity, thermostability, and large volume expansion during the charge–discharge process.

Optics express, 20(24), 27102-27107 (2012-11-29)

We report generation of femtosecond optical pulses tunable in the 1.6-2.5 μm range using GeO2-doped core silica-cladding fibers. Optical solitons with a duration of 80-160 fs have been measured by the FROG technique in the 2-2.3 μm range. To the

A hollow beam supercontinuum generation by the supermode superposition in a GeO2 doped triangular-core photonic crystal fiber.

Xin-ben Zhang et al.

Optics express, 20(18), 19799-19805 (2012-10-06)

A GeO2 doped triangular-core photonic-crystal fiber (PCF) is designed and fabricated to allow the generation of a hollow beam through a nonlinear-optical transformation by femtosecond pulses at 1040 nm from a high power Yb-doped PCF laser oscillator. The hollow beam
