Optical deposition of PtSe2 on fiber end face for Yb-doped mode-locked fiber laser

Two-Dimensional Platinum Diselenide: Synthesis, Emerging Applications, and Future Challenges

“…Since the pre-deposition process and post-selenization process are carried out in relatively mild condition, the PtSe 2 film can be prepared on arbitrary substrates. Besides the conventional Si [33,115,116], Si/SiO 2 [32,33,55,94,112,114,[117][118][119][120][121][122][123][124], and Sapphire substrate [81,125,126], 2D PtSe 2 film has been successfully grown on fused quartz [31,84,125], fluorine-doped tin oxide (FTO) [127,128], gallium nitride (GaN) [129], and polyimide [114]. Figure 8c shows the PtSe 2 on the surface of flexible polyimide [41,114].…”

“…Due to the nonlinear modulation from the PtSe 2 , the pulse duration of 861 fs and single-to-noise ratio of 61.1 dB were achieved for the 1567 nm mode-locking laser. The recent progresses on the PtSe 2 -based mode-locking laser make PtSe 2 a promising 2D material for on-chip integration of GHz laser sources toward higher repetition rates and shorter pulse duration [ 31 , 82 , 84 , 125 ].…”

Synthesis of 2D PtSe2 Nanolayers on Glass Substrates and Their Integration in Near-Infrared Light Shutters

“…To date, the majority of the reported PtSe 2 layers were synthesized by direct selenization of predeposited Pt thin layers via the TAC route. , Although large-area PtSe 2 thin layers can be synthesized by direct selenization through the TAC approach, it is still challenging to obtain PtSe 2 layers thin enough, below which the “semiconductor-to-semimetal” transition is expected to occur . Also, an important concern is the substrate selection, for example Si, − Si/SiO 2 , , fused quartz, − and sapphire are the most used, however, they are rather expensive. Besides these conventional substrates, the 2D PtSe 2 film has been successfully grown on gallium nitride, as well as on NaCl which after dissolution led to free-standing PtSe 2 films .…”
