Soliton logic gate using low-birefringence fiber in a nonlinear loop mirror
Optics Letters, 1995We demonstrate, using numerical simulations, a new all-optical logic gate that combines the mechanisms of soliton dragging and nonlinear-optical loop mirrors (NOLM’s). The design uses specially wrapped low-birefringence polarization-maintaining fiber, which we recently demonstrated in the NOLM configuration.

A fiber-optic temperature sensor based on a pressure-induced birefringence singlemode fiber (SMF) loop mirror is developed. The pressure-induced birefringence singlemode fiber is made by applying a force against a short section of length of a singlemode fiber. The length of the sensing element for the temperature sensing is about 50 mm.

Thulium-doped fiber laser using two FOLMs with a high birefringence fiber in the loop
SPIE Proceedings, 2017We report a linear cavity all-fiber Thulium-doped fiber (TDF) laser with tunable narrow linewidth operating near to 2 μm of wavelength. The TDF is pumped with a laser source at 1567 nm. The cavity is delimited by two fiber optical loop mirrors (FOLM) with high birefringence fiber in the loop (Hi-Bi FOLM) with different periodical wavelength-dependent ...

A fiber Bragg grating demodulation system using high-birefringence fiber loop mirror
SPIE Proceedings, 2014In this paper, a fiber Bragg grating (FBG) demodulation system based on high-birefringence fiber loop mirror (Hi-Bi FLM) is proposed and demonstrated. The approximate linear edge of the transmittance of the Hi-Bi FLM, which is a sinusoidal function of wavelength, is used to interrogate the sensing FBGs. The relationship between the wavelength period of

A fiber sensor configuration suitable for simultaneous measurement of temperature and strain is investigated. The sensor consists of a high-birefringence fiber loop mirror concatenating with an erbium-doped fiber. By monitoring the peak power variation and peak wavelength shift, it is feasible to simultaneously measure temperature and strain.

Application of high birefringence fiber Sagnac loop mirror in temperature sensing
SPIE Proceedings, 2007Experiments using high birefringence fiber Sagnac loop mirror as the temperature sensor are reported. We study the characteristics of this sensor based on intensity detection. The result is linear in the measurable range. The sensing sensitivities of temperature is 0.92nm/°C, which is nearly 89 times larger than the typical temperature sensitivities ...

A novel density sensor based on high-birefringence fiber loop mirror
SPIE Proceedings, 2013In this paper, a novel density sensor based on high-birefringence fiber loop mirror is proposed and studied. The high-birefringence fiber is pasted to a ring shaped rubber gasbag and placed in the liquid. Fasten the gasbag to the bottom of the container. When the density of liquid is changed, the liquid level keeps the same.
