Amplified Spontaneous Emission from Optical Fibers Containing Anisotropic Morphology CdSe/CdS Quantum Dots Under Continuous Wave Excitation

“…[39] Bahrampour et al investigated PbSe-doped fiber in a single-mode condition. [40] Also, numerous works that have been DOI: 10.1002/adpr.202300167 Fiber laser field is typically dominated by rare earth ions as gain material in the core of a silica optical waveguide. Due to their specific emission wavelengths, rare-earth-doped fiber lasers are available only at few predefined wavelengths.…”

“…reported on QD amplified spontaneous emission (ASE) have been obtained from colloidal QD medium and are obtained in closely packed thin films. [41][42][43][44][45] Moreover, most of the demonstrated ASE is pumped by femtosecond (fs) [20][21][22][23][24]40] or nanosecond pumping (quasi continuous wave (CW)) [24,[46][47][48] or using a cryostat setup. [46][47][48] Although there have been reports on ASE, lasing, and investigation of QDs containing optical fibers, however, not many reports are there about ASE from such specialty fibers.…”

Emission Kinetics from PbSe Quantum Dots in Glass Matrix at High Excitation Levels

“…Nevertheless, amplified spontaneous emission (ASE) and optical gain based on PbSe QDs (sol‐gel thin films or fiber structures) have been observed or predicted for ground‐state emission . More important, even stimulated emission was revealed in PbS:Glass with a relatively low f ‐value of 0.025% .…”

“…Nevertheless, amplified spontaneous emission (ASE) and optical gain based on PbSe QDs (sol-gel thin films or fiber structures) have been observed or predicted for ground-state emission. [11][12][13] More important, even stimulated emission was revealed in PbS:Glass with a relatively low f-value of 0.025%. [14] These reports suggest that the natural limitation of Pb-salt QDs for lasing application can be experimentally overcome, and PbSe:Glass with stronger quantum-confinement and elevated f-values could be suitable as lasing material, provided that the mechanisms leading to stimulated emission in QD:Glass can be addressed.…”
