Special Issue Information

Dear Colleagues,

Optical fiber technologies have achieved major advances in the last few decades, and have fundamentally reshaped the way we see, the way we sense, the way we communicate, and the way we live. They are especially well developed in the telecommunication industries and have great potential in new application fields such as sensing, lighting and industrial purposes. In addition to serving as transmission media, optical fibers have been used to realize several types of optical devices, namely optical amplifiers, broadband sources, optical sensors, and fiber lasers. These devices have the potential for widespread applications in different areas of science and technology. The rapid progress in optical fiber technology can be attributed to the continuous research efforts on the development of improved optical fibers, new optical devices, and new applications.

The aim of this Special Issue is to feature recent advances in the specialty optical fibers, optical fiber devices, and other applications, in terms of, but not limited to, fiber material and properties, design and fabrication, light localization structures, fiber surface functionalization through sensitive and/or transducing techniques, as well as fiber sensing systems.

It is our pleasure to invite you to contribute original full research papers, short communications, and state-of-the-art reviews to this Special Issue.

We demonstrate the production of a picosecond pulse from an Erbium laser cavity using black phosphorous (BP) on side-polished fiber saturable absorber (SA) as a mode-locker. The surface of the fiber was removed utilizing a polishing wheel, and then BP was mechanically deposited onto it to develop an excellent evanescent field on the polished surface area. The SA device was used in a 56 m long Erbium-doped fiber laser (EDFL) ring cavity to generate soliton mode-locked pulses with a center wavelength of 1556.2 nm and a 3 dB spectral bandwidth of 2.2 nm. Stable 3.48 MHz soliton pulses with pulse width as short as 1.17 ps were achievable by setting the pump power within 92 mW to 145 mW. The highest pulse energy and peak power obtainable were 5.4 nJ and 4.7 kW, respectively. The results show that BP deposited onto side-polished fiber can be used as an SA in an EDFL cavity. Its easy construction makes it suitable for producing a portable mode-locked laser source. Full article

We demonstrate a simple mode-locked Erbium-doped fiber laser (EDFL) based on self-synthesized saturable absorber (SA) by combining graphene oxide (GO) and polyethylene oxide (PEO) solutions to form a GO-PEO thin film. This thin film was incorporated into an Erbium-doped fiber laser (EDFL) with a cavity length of 9 m. Our EDFL could operate at a 22 MHz repetition rate with a 0.8 ps pulse duration. The laser also showed stable soliton pulses under various laser pump power values. Our reported results show that GO-PEO SA is effective and proven as a cost-effective material for saturable absorbers for EDFLs. Full article

Utilizing bismuth telluride (Bi2Te3) nanosheet saturable absorbers (SA), a remarkable source of continuous-wave infrared radiation known for its high efficiency and wide range of accessible wavelengths, has been successfully developed. The mode-locking bright pulses have a repetition frequency of 9.5 MHz and a pulse width of 0.6 ps at a power level of 203.5 mW. The optical spectrum has its center at 1050.23 nm and delivers pulse energies of 2.13 nJ and output power of 20.3 mW. Using a straightforward 18 m long ring design and a laser cavity with a −19.9 ps2/km dispersion, a 44 dB signal-to-noise ratio (SNR) was achieved to demonstrate the pulse’s strong stability.
