Journal ArticleDOI
Microfibre Mach-Zehnder interferometer and its application as a current sensor
TL;DR: In this article, a microfibre Mach-Zehnder interferometer (MMZI) was fabricated using flame-heated drawing technique, which shows good interference fringes with the highest extinction ratio of 14-dB.
Journal ArticleDOI
Performance comparison between plastic-based fiber bundle and multimode fused coupler as probes in displacement sensors
TL;DR: In this paper, the effects of axial displacements on the detected output voltages are also investigated for fiber bundle probe sensor, and the resolutions obtained are 0.9 and 4.0 μm, for the front and back slopes, respectively.
Journal ArticleDOI
2 μm passively mode-locked thulium-doped fiber lasers with Ta2AlC-deposited tapered and side-polished fibers.
TL;DR: In this paper, a mode-locked thulium-doped fiber laser operating in the 2µm wavelength region was demonstrated using tantalum aluminum carbide (Ta2AlC)-based saturable absorbers (SAs) utilizing the evanescent wave interaction.
Journal ArticleDOI
Tunable Radio Frequency Generation Using a Graphene-Based Single Longitudinal Mode Fiber Laser
TL;DR: In this paper, a single longitudinal mode (SLM) tunable erbium-doped fiber ring laser using a graphene-based saturable absorber is proposed and demonstrated as a tunable signal source.
