Experimental Performance of a Broadband Dual-Stage 1950 nm PM Single-Clad Tm-Doped Fiber Amplifier

Giant optical absorption of a PtSe2-on-silicon waveguide in mid-infrared wavelengths

“…1 To keep up with the increasing demand, the spectral expansion of optical communications and optical interconnects to the short-wavelength mid-infrared (SWMIR) band (2–2.5 μm) 2 has attracted tremendous research attention. To date, low-loss optical fibers 3 and amplifiers 4 have been commercialized in SWMIR wavelengths. Besides, silicon photonics provides a promising platform for developing high-performance SWMIR optoelectronic devices due to their advantages of low optical losses in this spectral region, cost-efficient device fabrication, and intrinsic compatibility with the complementary metal oxide semiconductor (CMOS) technology.…”

The gain and noise figure comparison of single‐pass, double‐pass, and dual‐stage triple‐pass thulium‐doped fiber amplifiers in S‐band with thulium‐doped fiber optimization

“…[22][23][24][25] When the literature is examined, it is seen that various studies have been carried out on multipass EDFA in C and L-bands. [26][27][28][29] On the other hand, there are studies on silica-based multi-pass TDFA in the L band and 1875-2000 nm band, 22,30 but there are no studies on silica-based TDFA in the S-band. This study is the first time that triple-pass TDFA is used in S-band.…”
