“…In addition, through the experimental scheme, the range of adjustment can be improved. The works reviewed to make the comparisons have the tuning ability in ranges between the 1080's-1090's nm using Ytterbiumdoped fiber (YDF) [13][14][15][16], 1530's-1560's nm with Erbiumdoped fiber (EDF) [17][18][19][20] and 1880's-1890's nm using Tm doped fiber [21][22][23], achieving this through mechanisms such as free-space, opto-fluidic or thermos-optic. This highlights the results obtained in our work where a fiber optic medium is used tuning through micrometric deflection and polarized light pumping achieving tuning in ranges between 1520's and 1550's.…”

This work presents a study of a deflection laser sensor using a pump light source with different polarization states, and shows that controlling the polarization state of the pump source can achieve better control in the tuning of an Erbium-doped Fiber Laser. Laser tuning uses a selective wavelength filter manufactured by means of a thin core fiber section between two single-mode fibers (TCFMI), whereas deflection is applied by means of an angular mechanism. In addition, the sensor was analyzed according to the wavelength shift of the laser emission as a function of the angular micrometric deflection, and a sensitivity of -33.01 pm/µrad was obtained in a dynamic range from 0 to 89.3 µrad with an adjustment parameter R2=0.99361. This sensor exhibits potential applications in the bionic and robotic detection fields owing to its high sensitivity, good linearity, simple fabrication, and low cost.

A singlemode-multimode-singlemode (SMS) fiber structure consists of a short section of multimode fiber fusionspliced between two SMS fibers. The mechanism underpinning the operation of an SMS fiber structure is multimode interference and associated self-imaging. SMS structures can be used in a variety of optical fiber systems but are most commonly used as sensors for a variety of parameters, ranging from macro-world measurands such as temperature, strain, vibration, flow rate, RI and humidity to the micro-world with measurands such as proteins, pathogens, DNA, and specific molecules. While traditional SMS structures employ a short section of standard multimode fiber, a large number of structures have been investigated and demonstrated over the last decade involving the replacement of the multimode fiber section with alternatives such as a hollow core fiber or a tapered fiber. The objective of replacing the multimode fiber has most often been to allow sensing of different measurands or to improve sensitivity. In this paper, several different categories of SMS fiber structures, including traditional SMS, modified SMS and tapered SMS fiber structures are discussed with some theoretical underpinning and reviews of a wide variety of sensing examples and recent advances. The paper then summarizes and compares the performances of a variety of sensors which have been published under a number of headings. The paper concludes by considering the challenges faced by SMS based sensing schemes in terms of their deployment in real world applications and discusses possible future developments of SMS fiber sensors.

Herein, the main aspects of fiber lasers are summarized where multimode interference (MMI) is the underlying phenomenon for the wavelength tuning mechanism. Also, 15 years of work in the field are covered, from its first report, in 2005, to the most recent publications, in 2020. In addition to the historical perspective, insights into the different mechanisms are also provided that are exploited to tune the spectral response of the MMI filters used in fiber lasers, among which are free space, optofluidic, stress optic, thermo optic, and nonlinear mechanisms.
