“…The melts were then quenched on a preheated stainless steel plate and followed by annealing at 350 C for 5 h in order to release the thermal stresses. After annealing, samples for optical and spectral properties measurements were cut into rectangular 30 Â 20 Â 2 mm 3 shapes and polished to optical quality.…”

“…To meet the requirement of present and future optical telecommunication and other data transmitting services, considerable efforts have devoted to expanding the usable gain bandwidth and gain coefficient for wavelength division multiplexing (WDM) transmission systems. [1][2][3] Rare-earth (RE) ions doped fiber amplifier and Raman fiber amplifier (RFA) are expected to greatly increase the capacity of WDM systems. Compared to RE doped fiber amplifier, RFA has a lot of excellent features.…”

In order to obtain broadband and high Raman gain coefficient in the tellurite glass, a detailed study of the effects of WO 3 , MoO 3 , and P 2 O 5 in TeO 2-ZnO-Na 2 O-Nb 2 O 5 (TZNN) glass system on the thermal stabilities and Raman spectroscopic was performed. It was found that both WO 3 and MoO 3 improved the glass thermal stability and enhanced the bandwidth significantly. Higher Raman gain coefficients and broader bandwidth were realized in the MoO 3 modified glasses than those of WO 3 added glass. The tellurite glass containing 15 mol. % MoO 3 exhibits the bandwidth 1.7 times larger than the silica glass and the Raman gain coefficient is as high as 38 times that of the silica glass. Moreover, with the addition of P 2 O 5 in TeO 2-ZnO-Na 2 O-Nb 2 O 5-WO 3 (TZNNW) and TeO 2-ZnO-Na 2 O-Nb 2 O 5-MoO 3 (TZNNM) glass systems, the thermal stabilities can further be improved. On the other hand, the Raman bandwidth can further be broadened, especially in the TZNNMP glass system. The tellurite glass containing 15 mol. % MoO 3 and 15 mol. % P 2 O 5 shows the bandwidth 1.9 times larger than the silica glass and maintains high Raman gain coefficient which is as high as 37 times that of the silica glass, indicating this glass is a promising candidate as new gain media for broadband Raman fiber amplifier.

“…The increase of dopant content in Ge-and P-doped silica fibers with a simultaneous reduction of optical losses seems the most straightforward solution to the first problem. The second option is to use multicomponent glasses, including heavy-metal oxides-doped glasses, which also permits the development of glasses with the Raman gain bandwidth of several hundreds of cm −1 [37][38][39][40][41][42]. However, in multicomponent glass approach the current limitation is to obtain low-loss fibers.…”

Nowadays, in fiber optic communications the growing demand in terms of transmission capacity has been fulfilling the entire spectral band of the erbium-doped fiber amplifiers (EDFAs). This dramatic increase in bandwidth rules out the use of EDFAs, leaving fiber Raman amplifiers (FRAs) as the key devices for future amplification requirements. On the other hand, in the field of high-power fiber lasers, a very attractive option is provided by fiber Raman lasers (FRLs), due to their high output power, high efficiency and broad gain bandwidth, covering almost the entire near-infrared region. This paper reviews the challenges, achievements and perspectives of both fiber Raman amplifier and fiber Raman laser. They are enabling technologies for implementation of high-capacity optical communication systems and for the realization of high power fiber lasers, respectively.

Important accomplishments concerning an integrated laser source based on stimulated Raman scattering (SRS) have been achieved in the last two decades in the fields of photonics, microphotonics and nanophotonics. In 2005, the first integrated silicon laser based upon SRS was realized in the nonlinear waveguide. This breakthrough promoted an intense research activity addressed to the realization of integrated Raman sources in photonics microstructures, like microcavities and photonics crystals. In 2012, a giant Raman gain in silicon nanocrystals was measured for the first time. Starting from this impressive result, some promising devices have recently been realized combining nanocrystals and microphotonics structures. Of course, the development of integrated Raman sources has been influenced by the trend of photonics towards the nano-world, which started from the nonlinear waveguide, going through microphotonics structures, and finally coming to nanophotonics. Therefore, in this review, the challenges, achievements and perspectives of an integrated laser source based on SRS in the last two decades are reviewed, side by side with the trend towards nanophotonics. The reported results point out promising perspectives for integrated micro- and/or nano-Raman lasers.
