Nonlinear Few‐Layer MXene‐Assisted All‐Optical Wavelength Conversion at Telecommunication Band

Abstract: logic operations, and buffering, are still lacking in practically usable forms. It is still challenging to improve the optical device performance for practical applications, including reducing footprint size, required optical power levels, and device performance regarding nonlinear transfer characteristics. Wavelength conversion between adjacent channels is one of the essential functions in advanced optical networks. As a crucial component in the optical communication system, alloptical wavelength converter sh… Show more

“…2. 2D PtSe 2 has been theoretically predicted to be a promising candidate to fabricate high-performance electronic and optoelectronic devices [211][212][213][214][215][216][217][218][219][220][221][222][223][224]. Although some pioneer works have been reported, the performance of 2D PtSe 2 -based devices are stills much lower than theoretical prediction.…”

“…Recently, MXene NLO devices have been also demonstrated, for example, (a) ultrafast mode‐locked fiber lasers in the near‐infrared (NIR) regime that leveraged the saturable absorption of MXenes (Ti 3 CNT x , Ti 3 C 2 T x , Ti 2 CT x , and Mo 2 C); (b) photonic diode due to the low threshold of saturable absorption of Ti 3 C 2 T x MXene; (c) all‐optical modulator and switcher based on the spatial self‐phase modulation (SSPM) and cross‐phase modulation (XPM) effects of Ti 3 C 2 T x MXene; and (d) wavelength conversion at telecommunication band through the four‐wave mixing employing Ti 3 C 2 T x . Because of the outstanding performance of Ti 3 C 2 T x in nonlinear devices, it is important to investigate the NLO properties of other MXenes such as Ti 2 CT x .…”

“…2D materials have become a hot topic in the academic field due to their atomic layer thickness, broadband absorption and ultrafast optical response, which has been widely applied in the ultrafast laser generation, [103][104][105][106][107][108][109] optical switching and modulators, [110][111][112][113][114][115][116] optoelectronics devices, [106,[117][118][119] and biosensor and biotherapy. [120][121][122][123][124][125][126][127][128][129] In contrast to the significant progress in synthesizing 0D and 1D Se nanostructures, much less is known on 2D Se nanostructures, their processing approaches, and related properties so far.…”
