PbO–GeO2 rib waveguides for photonic applications

“…For example, the propagation loss for a Si 3 N 4 rib waveguide with different dimensions, rib height of 0.002 m and width of 3-5 m, is 2.2 dB/cm for 633 nm [27] for single mode operation. Another example that should be considered is the propagation loss of a Na 2 O-MgO-Al 2 O 3 -GeO 2 rib waveguide with height of 0.2 m and width of 12 m for multimode operation: 0.48 dB/cm for 1482 nm [28]. In this case the difference may be attributed to the fact that propagation losses for 633 nm are normally much higher than in the infrared region due to Rayleigh scattering [29].…”

Triply-doped germanate glasses for ultra-broadband optical devices

“…Non-oxide glasses, such as fluoride and sulfide glasses, have ultra-low phonon energy, but their long-term chemical stabilities and high toxicity problems still limit the practical applications of these non-oxide glasses. Aluminum germanate (NMAG) oxide glasses exhibit good thermal stability and medium-low phonon energy (<900cm −1 ), and in our previous work high-quality acid-resistant NMAG glasses (with 53 mol% GeO 2 ) possessing high UV photosensitivity have been fabricated successfully, and Er 3+ and Tm 3+ singly doped ionexchanged waveguides have been demonstrated 6,7 .…”

Ion-exchanged Tm^3+:glass channel waveguide laser

“…We have recently demonstrated multi-GHz repetition rate, femtosecond operation of an ion-exchanged Yb:glass waveguide laser at 1 μm [17] and extension of this work to 2 μm would open up opportunities such as pumping of mid-infrared frequency combs [18]. However, to date there have been very limited reports [19,20] of ionexchanged Tm 3 glass waveguides and a focus has been on amplification near 1.5 μm [20].…”
