Multiwavelength Raman fiber laser based on a highly birefringent photonic crystal fiber loop mirror
SPIE Proceedings, 2010In this work, a multiwavelength Raman fiber laser based on a highly birefringent photonic crystal fiber is presented. A laser resonator is formed when the Raman amplification with cooperative Rayleigh scattering in a dispersion compensating fiber is used as a distributed mirror and combined with a highly birefringent photonic crystal fiber loop ...

Reflective semiconductor optical amplifier pattern effect compensation with birefringent fiber loop
Optical and Quantum Electronics, 2020We experimentally explore and demonstrate the potential of a birefringent fiber loop (BFL) to compensate for the pattern effects (PE) induced in a reflective semiconductor optical amplifier (RSOA), which is driven by optical data whose intensity, temporal and spectral characteristics heavily stress the RSOA.

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 ...

Strain and Temperature Discrimination Using Concatenated High-Birefringence Fiber Loop Mirrors
IEEE Photonics Technology Letters, 2007In this letter, a new configuration for simultaneous strain and temperature discrimination is presented using two concatenated high-birefringence (Hi-Bi) fiber loop mirrors. The first loop mirror includes a Hi-Bi photonic crystal fiber, while the second one contains a length of internal elliptical cladding fiber.

Tunable Multiwavelength Fiber Ring Lasers Using a Programmable High-Birefringence Fiber Loop Mirror
IEEE Photonics Technology Letters, 2004We demonstrate a comb filter with digitally tunable wavelength spacing using a programmable high-birefringence (HiBi) fiber loop mirror (FLM). We then use the HiBi-FLM to implement a tunable multiwavelength semiconductor optical amplifier (SOA)-based fiber ring laser and a tunable multiwavelength all-fiber Raman ring laser.

Curvature sensor based on low-birefringence photonic crystal fiber Sagnac loop
2010 Photonics Global Conference, 2010A fiber optic curvature sensor with low-birefringence photonic crystal fiber (PCF) based Sagnac loop is demonstrated experimentally. The low-birefringence PCF is about 40cm long, using as the sensing element. The Sagnac output spectra under different curvatures are measured and analyzed.

Highly birefringent photonic bandgap Bragg fiber loop mirror for sensing applications
SPIE Proceedings, 2011A highly-birefringent photonic bandgap Bragg fiber loop mirror sensor is proposed. Thanks to the Bragg fiber geometry, one can observe the group birefringence and the bandgap fiber in the transfer function. The sensing head presented different sensitivities for strain and temperature measurements.
