“…In another approach, cellulose derivatives (polymer) were used as a dispersion agent to achieve the initial aquatic dispersion of SWNTs. Finally, resulting dispersions were mixed with the water-soluble polymer such as polyvinyl alcohol (PVA) [168,169], cellulose derivatives [69] or polyethylene oxide (PEO) [170] and dried in order to achieve a freestanding film.…”

“…The pioneering research was focused on the application of mirrors and fibre ferrules with a sprayed solution of CNTs [208] or by direct growth of the CNT in a substrate [209]. However, the most straightforward method is utilisation of CNT-polymer films sandwiched between fibre ferrule connectors or fibre ends [51,69,210].…”

“…The pioneer works on Tm-doped fibre lasers mode locked with SWNTs used ferrule-type SA [69], or fibre tapers embedded in an SWNT/polymer composite [63]. Here, we would like to pay more attention to the other approach, allowing high-quality ultrashort pulse formation.…”

Carbon nanotubes (CNTs) possess both remarkable optical properties and high potential for integration in various photonic devices. We overview, here, recent progress in CNT applications in fibre optics putting particular emphasis on fibre lasers. We discuss fabrication and characterisation of different CNTs, development of CNTbased saturable absorbers (CNT-SA), their integration and operation in fibre laser cavities putting emphasis on stateof-the-art fibre lasers, mode locked using CNT-SA. We discuss new design concepts of high-performance ultrafast operation fibre lasers covering ytterbium (Yb), bismuth (Bi), erbium (Er), thulium (Tm) and holmium (Ho)-doped fibre lasers.

“…It was successfully demonstrated by using different kind of saturable absorbers (SAs). There are a lot SAs that been used to generate the laser such as graphene [6], single-walled carbon nanotubes (MWCNTs) [15], [16] and semiconductor saturable absorber mirrors (SESAMs) [17]. However, SESAMs cannot be used widely due to the complexity of fabrication and not cost effective.…”

Abstract-We demonstrate an ultrafast TDFL Q-switched pulse in 2 µm wavelength using multi-walled carbon nanotubes (MWCNTs) as passive saturable absorber (SA). MWCNTs film is sandwiched between two fibre connectors or patch cords after deposited with index matching gel on the fibre ferrules. Thulium-doped fibre was pumped using 1552 nm source in the ring cavity. The repetition rate for the pulses can be tuned from 13.33 kHz to 21.07 kHz by varying the pump power from 307.5 mW to 371.4 mW. At the maximum power, the pulse generated energy of 87.34 nJ with full-width at half maximum (FHWM) of 8.21 µs.Index Terms-Multi-walled carbon nanotubes, passive saturabe absorber, Q-switching.

“…6 Different approaches have been pursued to obtain mid-infrared frequency combs. [7][8][9][10][11] One possibility is the use of mode-locked lasers, which are also of considerable interest for their ability to generate ultra-short light pulses at high repetition rates. Mode locking of lasers has been a subject of intense research because of the complex nonlinear dynamics involving the self-organization of many laser modes.…”

Optimizing the active region of interband cascade lasers for passive mode-locking

et al. 2017

View full text Add to dashboard Cite

The work proposes possible designs of active regions for a mode-locked interband cascade laser emitting in the mid infrared. For that purpose we investigated the electronic structure properties of respectively modified GaSb-based type II W-shaped quantum wells, including the effect of external bias in order to simultaneously fulfil the requirements for both the absorber as well as the gain sections of a device. The results show that introducing multiple InAs layers in type II InAs/GaInSb quantum wells or introducing a tensely-strained GaAsSb layer into “W-shaped” type II QWs offers significant difference in optical transitions’ oscillator strengths (characteristic lifetimes) of the two oppositely polarized parts of such a laser, being promising for utilization in mode-locked devices.
