“…[12] designed a hybrid plasmonic waveguide with guided mode confined mainly into outer high-index slab, and the waveguide consisted of 5 nm-thick Au stripe and flexible multiple polymer cladding layers, the radiation loss due to bending was greatly suppressed. An SOI waveguide core size (440 nm ×220 nm) was proposed with a bending radius of 1.0 µm and substrate multilayers of Si/SiO 2 , the bending loss reduction of the quasi-TM-mode up to ∼2.5 dB/90 • [13].

We propose a surface-plasmonic right-angle bend waveguide with bismuth ion-doped glass film as core layer and Ag films as cladding layers for first time, to the best of our knowledge. Theoretical analysis shows that the right-angle has bend and absorption losses of 3.17 dB. The rate equations and power evolution equations of high concentration bismuth-doped glass film are setup and solved to analyze the effect of the waveguide length and active ion concentration on the signal gain and Noise Figure (NF). The theoretical results predict that with the pump power 100 mW, the active ion concentration 2.0×10 26 ions/m 3 and the right-angle waveguide size 1.0 cm×1.0 cm, small-signal unit-length net gain can reach 15.32 dB with NF less than 5.0 dB.
