A mode-locked, dual-wavelength pumped 3.5 μ m fiber laser using frequency shifted feedback utilizing an acousto-optic modulator is reported. Pulses of 3.8 ps with 9.7 nJ were obtained at a repetit…
We introduce a method of inscribing in-fiber devices using a femtosecond laser that is applicable to crucial components, such as cladding waveguides (CWGs), cladding Mach-Zehnder interferometers (M…
We consider the excitation of leaky mode resonances (LMRs) in an optical fiber that originate from light coupling initiated by small angle (
In this article, we present an investigation of a multimode fiber interferometer based on a multimode gradient index perfluorinated polymer fiber. The interferometric response of the polymer fiber …
