Polarization-independent DPSK demodulation using a birefringent fiber loop

IEEE Photonics Technology Letters, 2005
A robust polarization-independent technique for demodulating optical differential phase-shift-keying (DPSK) signals using a birefringent-fiber-loop (BFL) is proposed and demonstrated. The BFL has a differential group delay between its fast and slow optical axes, providing interference which allows the phase modulation to be converted to intensity ...

High-Birefringent Fiber Loop Mirror Sensors With an Output Port Probe

IEEE Photonics Technology Letters, 2011
Two new configurations of high-birefringent fiber loop mirror with an output port probe are proposed. The two configurations used two couplers spliced between them with unbalanced arms and one output port is used as the probe sensor. The difference between them is that the section length of high-birefringent fiber is located between the two couplers ...

High-birefringence fiber loop mirrors and their applications as sensors

Applied Optics, 2005
The reflection and transmission characteristics of a high-birefringence fiber loop mirror (HiBi-FLM), which is composed of a standard fiber coupler and one-section or multisection high-birefringence fibers (HBFs), are analyzed and discussed in detail.

Liquid-level sensor with a high-birefringence-fiber loop mirror

Applied Optics, 2006
A novel liquid-level sensor with a high-birefringence-fiber loop mirror (HBFLM) based on a uniform-strength cantilever beam (UCB) is proposed and demonstrated. Part of the high-birefringence fiber is pasted onto the central surface of the UCB. A hollow suspending pole is utilized to apply force at the end of the beam.
