A compact fiber polarizer is demonstrated by the filling of selected air holes of a hollow-core photonic crystal fiber (PCF) with a liquid. The liquid-filling results in an asymmetric waveguide struct...
A fiber loop mirror (FLM) temperature sensor using a long-period grating (LPG) written in a photonic crystal fiber (PCF) and a band-pass filter as a demodulator is proposed. By utilizing the stable fi...
A highly sensitive strain sensor is demonstrated by introducing a photonic crystal fiber (PCF) Mach–Zehnder interferometer (MZI) in a cavity ringdown fiber loop as a sensing element. The MZI is fabric...
An optical fi ber twist sensor is proposed by using solid core low birefringence photonic crystal fi ber (LB-PCF)-based Sagnac interferometer. The twist effects on the fi ber are theoret-ically analyz...
A compact temperature sensor based on a fiber loop mirror (FLM) combined with an alcohol-filled high-birefringence photonic crystal fiber (PCF) is proposed and experimentally demonstrated. The output ...
Increasing input chirp decelerates (accelerates) the spectral recoiling process across a negative dispersion slope for pulses experiencing normal (anomalous) dispersion. A realistic defect-core photon...
We experimentally demonstrate 7dB improvement in Brillouin suppression in a photonic crystal fiber by periodically varying the size of the air-hole-structure by only 7% amplitude while keeping a low a...
An optical fiber transverse mechanical load sensor is fabricated by using a short section of a solid core photonic crystal fiber (PCF) which is inserted inside a Sagnac fiber loop. An initial transver...
An optical fiber strain sensor by using a low-birefrin-gence photonic crystal fiber (PCF)-based Sagnac loop is demon-strated. A fiber Sagnac loop is formed by the low-birefringence PCF of about 40 cm,...
A fi ber-optic strain sensor is demons trated by using a short length of highly birefringent phot onic crystal fi ber (HiBi-PCF) as the sensing element inserted in a fi ber loop mirror (FLM). Due to t...
We propose and demonstrate a novel method to characterize the variation of the birefringence induced by structural irregularities in highly birefringent photonic crystal fiber with high accuracy based...
We demonstrate polarization-insensitive wavelength multicasting of RZ-DPSK signal. The input signal is copied to four different wavelengths using four-wave mixing with unequally spaced pumps in a disp...
We demonstrate a 10-Gbit/s transmission over a 5-km photonic crystal fiber in the 1.1 μm band using a directly-modulated single-mode VCSEL. The transmission distance was extended to 14 km by using an ...
We have fabricated a photonic crystal fiber based Mach-Zehnder interferometer and demonstrated its use in both RZ-to-NRZ and NRZ-to-PRZ pulse format conversions for 10-Gb/s OOK signals.The PCF length ...
We demonstrate simultaneous time and wavelength multicasting with NRZ to RZ format conversion by four-wave mixing of the input signal with a time- and wavelength-interleaved laser source. Error-free o...
