“…However, erbium ions have a small gain bandwidth and a fixed working band that fail to satisfy the communication demands. It was demonstrated that PbSe quantum dots (QDs) are excellent gain media for broadband amplification in amplifiers owing to their spectral coverage in the near-infrared region, tunable absorption-emission spectra, and high quantum yields [27][28][29]. To our knowledge, few studies have focused on the OAM amplification based on the PbSe QDs with OAM amplifiers.…”

Vortex beams carrying orbital angular momentum (OAM) have increasingly attracted attention in the field of optical communication. However, transmission is still an issue due to transmission loss, especially in optical fibers. In this work, we proposed, designed, and fabricated micro spiral phase plates (SPPs) directly on an end facet of a piece of PbSe-doped ring-core fiber (RCF) through two-photon polymerization, realizing the integration of OAM beam generation, transmission, and amplification. The prepared RCF comprises a double-clad structure with a core-clad refractive index difference of 2.2% and the fluorescence range is 1150 nm–1700 nm. The intensity distribution of the OAM beam and the spiral interference fringes were obtained, which indicated that the OAM mode () was generated and transmitted directly within the fiber. The small-signal amplification of four OAM modes was accomplished at 1550 nm under a pump power of 634 mW. The on–off gain is >13.2 dB for all modes and the differential mode gain (DMG) is <1.7 dB. The SPP-carrying RCF structure demonstrates the integration of generation, transmission, and amplification of higher-order OAM modes in all-fiber systems.

“…By allowing only reduced transmission to the target area while exhibiting high transmittance for low ambient light, human eyes and optical devices are protected from hazardous and intense laser radiation [1][2][3][4][5][6][7][8][9][10][11][12]. Some extensively investigated OL materials include organic dyes (e.g., phthalocyanine and porphyrin) [1][2][3], carbon-based materials (e.g., carbon nanotubes, fullerenes, and graphene) [4][5][6], metal and semiconductor nanoparticles (NPs) [7][8][9], and quantum dots [10][11][12]. Unfortunately, single OL materials cannot meet the following requirements of ideal OL materials: large nonlinear optical effect, low OL threshold, high damage threshold, rapid response speed, broadband spectral response, and environmental and mechanical stabilities.…”

“…Indium selenide crystals possess a high conductivity [11] and may show potential applications in optoelectronic device such as lasers, light emitting diodes (LEDs) and solar cells [12]. The PbSe crystalline phase possesses nonlinear optical properties [13][14][15][16] and could also present an interest for photovoltaic applications [17,18]. The work presented in this study focuses only on the exploration of the chalcogenide glass compositions containing indium or lead and their thermal, optical and mechanical properties.…”

Two new chalcogenide glassy domains were explored by substituting Ga for In or Pb in compositions from the GeSe 2 -Ga 2 Se 3 tie line in the Ge-Ga-Se ternary diagram. The thermal, optical and mechanical properties of these glasses were determined and the effect of the substitutions on these properties was assessed. It is shown that addition of lead tends to destabilize the glasses while the addition of indium tends to stabilize them. Both elements induce a systematic increase in the onset of transmission values and in the densities when substituted to gallium. The glasses synthesized represent good potential candidates for the production of glass-ceramics with photovoltaic or nonlinear properties.
