Optical amplification and laser spectroscopy of neodymium-doped fluoride glass channel waveguides

We report on the first observation of optical signal amplification at 1.047 μm in neodymium-doped fluoride glass channel waveguides. Up to 2.7 dBcm−1 signal amplification (internal gain) at 1.047 μm has been obtained with absorbed power of 7 mW at 795 nm. This result demonstrates the ability of rare...

Description
Summary:We report on the first observation of optical signal amplification at 1.047 μm in neodymium-doped fluoride glass channel waveguides. Up to 2.7 dBcm−1 signal amplification (internal gain) at 1.047 μm has been obtained with absorbed power of 7 mW at 795 nm. This result demonstrates the ability of rare earth (RE) doped heavy-metal fluoride glasses to serve as active waveguides for integrated optics.
