We propose a dual-core photonic crystal fiber (PCF) for a broad bandwidth polarization-insensitive coupler. To achieve ultrabroadband and polarization-insensitive characteristics, two elliptical fluorine-doped cores are introduced. By optimizing structure parameters and fiber length, a polarization-insensitive 50:50 coupler is achieved. Its coupling ratio stabilizes at 50 ± 1% the in whole optical...
In this paper, a compact 10 dB E-Plane waveguide directional coupler with full bandwidth is presented. This construction covers the frequency from 6.5 to 10 GHz. Its coupling value is 10±1 dB, and the isolation is greater than 43 dB, which means that the directivity is in excess of 30 dB.
A terahertz (THZ) cross-guide waveguide directional coupler with high directivity is realized in this paper. This construction covers the frequency from 205 to 235 GHz. Its coupling value is 20±0.8 dB, and the isolation is greater than 51 dB, which means that the directivity is in excess of 30 dB.

This paper presents some key issues in fiber-optic interferometric magnetic field sensors. Practically applicable methods to design and implement fiber-optic Michelson interferometer and transducers are described with experimental verifications. Detection scheme of traditional hardware demodulation is improved, and a new software demodulation method is addressed. Transducers were implemented by using...
