“…Yui et al developed a PCF-SPR sensor for SiO 2 gas, which consists of a large air hole in the optical ber as the sensing channel. The sensitivity of this sensor for SiO 2 was 1.99 nm/% [10].Wei et al designed a D-type PCF-SPR sensor using gold nanorods to excite the SPR in methane detection, which was able to detect an average wavelength sensitivity of 4.26 nm/% at a higher wavelength range of 1.8 to 2.3 µm wavelength [11].Ranju Sardar et al found out a hollow core photonic crystal ber (HC-PCF) based gas sensor for monitoring carbon dioxide (CO 2 ).This optimal design provides the relative sensitivity of 93.5% with a con nement loss of 0.004 dB/m at λ = 2.65 µm the absorption wavelength of CO 2 [12].

This paper presents a gas sensor that uses surface plasmon resonance (SPR) technology and a novel D-type photonic crystal fiber (PCF) structure to detect methane. The sensor's double-sided, side-polished gas holes are the key components for achieving large-area contact with external methane gas. The coating material chosen to stimulate the SPR effect was a gold nanolayer. To increase the sensitivity of methane gas detection, the researchers used polysiloxane-doped cryptane E as a coating material. The study analyzed the sensor characteristics using finite element analysis (FEA) and numerical analysis to examine the effect of optical structure parameters on the sensor performance. The numerical results demonstrate that the sensor has a sensitivity of 11.52 nm/% and a FOM value of 0.409 when measuring methane gas in the concentration range of 0–3.5%. The curve fitted shows excellent linearity. The sensor is a promising technology for the future development of gas leakage detection due to its low cost, simplicity, and real-time detection capability.

“…Dual-wavelength Q-switched fibre laser is a highly adaptable light source that can emit more than a single discrete laser emission line. While, switchable dual-wavelength fibre laser implies the ability to adjust the laser emission rapidly and discretely from one fixed wavelength to another predefined wavelength, which has drawn significant attention in various fields of applications, including biomedical research (Al-Karadaghi et al, 2015), fibre optic sensing (Du et al, 2019;Yin et al, 2019;Arman & Olyaee, 2021;Sardar et al, 2021), millimetre wave (Yu et al, 2006), optical communication systems, microwave photonics (Yao et al, 2006;Pan & Yao, 2009b;Pan & Yao, 2009a;Jiang et al, 2011;Wang et al, 2015), remote sensing instruments (Sharma et al, 2004;Han et al, 2005), spectroscopy (Krzempek et al, 2013) and terahertz signal (Gu et al, 1998;Kleine-Ostmann & Nagatsuma, 2011;Tang et al, 2011;Soltanian et al, 2015).…”

This work aims to study the dual-wavelength Q-switched fibre laser performances with erbium-doped fibre as the gain medium and the fibre Bragg gratings to allow stable switchable dual-wavelength states. Spider silk was used as an alternative biological material for saturable absorber. The spider silk as a saturable absorber was prepared by directly sandwiched between the surface of fibre ferrules. A dual-wavelength system operating at 1550 nm and 1560 nm was generated by modulating the polarisation controller to regulate the mode competition in the ring cavity. This allows for a flexible switch between individual wavelengths of 1550 nm or 1560 nm. The device operates at a wavelength of 1550 nm, with 26.63 kHz repetition rate and 9.45 μs pulse width. At a wavelength of 1560 nm, it produces a repetition rate of 24 kHz and a pulse width of 10.47 μs. The output demonstrated consistent stability throughout time, with no changes recorded. This indicates a stable signal-to-noise ratio of 41.12 dB and 34 dB for wavelengths 1550 nm and 1560 nm, respectively. This study presents the latest approach using spider silk as a saturable absorber to create a dual-wavelength Q-switched fibre laser. The laser is based on a fibre Bragg gratings device and has potential uses in terahertz signal and laser radar.

“…Although various photonic crystal ber-based sensors have been suggested in the literature, the structural arrangement is commonly homogeneous that limits the operating wavelength and the type of analyte to be sensed [27][28][29]. On a very basic level, the structural arrangement of core and cladding in PCF resolve the operating wavelength, sensitivity, absorbance, birefringence, number of modes, dispersing, con nement loss, non-linearity, effective area, and polarization [31][32][33][34][35][36]. Hence, this paper proposes a hybrid arrangement of circular and hexagonal holes in the arrangement of honeycomb.…”

A hybrid structured honey-comb photonic crystal ber sensor is designed to detect the sensitivity of methyl salicylate (C 8 H 8 O 3 ), arsenic trichloride (AsCl 3 ), and ethylbenzene (C 8 H 10 ) analytes. The cladding portion of the proposed structure consists of both circular and hexagonal holes in the form of a hexagon with a honeycomb arrangement. Moreover, the structure has a circular core with the chosen analyte. The design is investigated in the scope of wavelength ranging from 0.4 µm to 1.75 µm. The hybrid photonic crystal ber sensor displays a sensitivity of 85.05%, 87.89%, 82.73% for methyl salicylate, arsenic trichloride, and ethylbenzene, respectively at 1.550 µm.
