1537 nm Emission Upon 980 nm Pumping in PbSe Quantum Dots Doped Optical Fiber

Lead Chalcogenide Quantum Dot‐Doped Glasses for Photonic Devices

“…40 Guo et al 41 theoretically demonstrated PbS QDs-coated tapered fiber amplifier can provide an optical gain of 10.5 dB with a band width of~160 nm centered at~1530 nm range. In addition, experimental works on silica microstructured optical fibers (MOFs) with PbS QDs coating 42 tapered single mode fiber coated with PbS QDs, 43 PbSe or PbS quantum dotsdoped optical fibers 44,45 have been reported.…”

Morphology‐Tailored Synthesis of PbSe Nanocrystals and Thin Films from Bis[N,N‐diisobutyl‐N′‐(4‐nitrobenzoyl)selenoureato]lead(II)

“…[1] Strong confinement of the electron-hole pair results in a large optical nonlinearity. [2] Lead selenide particles or thin films with critical dimensions best measured in nanometres have potential for application in optical switches, [2][3][4] communication devices, [5][6][7][8][9] photovoltaic cells, [10][11][12][13][14][15][16][17][18][19][20][21][22] biological imaging [23][24][25][26][27][28] and photodetectors. [29][30][31][32][33][34][35][36] Murray et al first synthesized monodispersed PbSe quantum dots, [37] but a number of other strategies have now been developed.…”

Enhanced thermal stability of oleic-acid-capped PbS quantum dot optical fiber amplifier

“…For example, PbSe QDs were doped into silica optical fibers by using modified chemical vapor deposition (MCVD) technology, and an amplified spontaneous emission at 1537 nm has been achieved [12]. By filling the PbSe QD solution into a photonic bandgap fiber, PL at 1554 nm has been observed [13].…”
