Mode-selective couplers for few-mode optical fiber networks
Optics Letters, 2012 The excitation and separation of individual modes in a few-mode optical fiber network can be realized using mode-selective couplers. For excitation at the beginning of the fiber, two-core mode-selective couplers can be used, while at the end of the fiber, either two- or three-core mode-selective couplers are required for demultiplexing of the field ...

High-Order Mode Mode-Locked Fiber Laser Based on Few-Mode Saturable Absorber
IEEE Photonics Journal, 2021 We presented two kinds of high-order mode (HOM) mode-locked fiber lasers based on few-mode (FM) saturable absorbers for direct HOM oscillation. One is a ring fiber laser based on a carbon nanotube (CNT) saturable absorber (SA), in which the combination ...

Intensity-only-measurement mode decomposition in few-mode fibers [PDF]
Optics Express, 2021 Recovery of optical phases using direct intensity detection methods is an ill-posed problem and some prior information is required to regularize it. In the case of multi-mode fibers, the known structure of eigenmodes is used to recover optical field and find mode decomposition by measuring intensity distribution.

Few-mode elastomeric optical fibers
Optical Materials Express, 2021 We present a new approach for producing elastomeric optical fibers with an optical behaviour corresponding to a few-mode optical fiber. Different fibers have been produced by first fabricating thermoplastic polyurethane preforms and subsequently drawing them.

A Few Mode Fiber Temperature Sensor Filled With PDMS Based on Vernier Effect
IEEE Photonics Journal, 2021 A few mode fiber temperature sensor filled with PDMS based on vernier effect is proposed. It uses single mode fiber (SMF), few mode fiber (FMF), and polydimethylsiloxane (PDMS) to form the SMF-air microcavity-FMF-PDMS-FMF structure.
