Optics Letters
|July 1, 2022
Summary
We developed a novel hybrid splicing technique to connect hollow-core and solid-core polarization-maintaining fibers. This method achieves low loss and high polarization extinction ratio, enabling advanced applications.
Area of Science:
- Optics and Photonics
- Materials Science
Background:
- High-performance fiber interconnections are crucial for advanced optical systems.
- Polarization-maintaining hollow-core fibers (PM-HCF) offer unique advantages but require robust connection methods.
Purpose of the Study:
- To develop a hybrid splicing approach for low-loss, low-backreflection, and high-polarization extinction ratio (PER) interconnection between PM-HCF and solid-core fiber (SCF).
Main Methods:
- A hybrid cold/heat two-step splicing process was employed.
- The interconnection utilized a high-birefringence PM-HCF and a commercial Panda SCF.
Main Results:
- Achieved simultaneous low backreflection (< -35 dB), low insertion loss (∼0.7 dB), and high PER (∼27 dB).
- This represents the first reported high-performance interconnection between PM-HCF and Panda SCF.
Conclusions:
- The developed hybrid splicing technique enables high-performance PM-HCF/SCF interconnections.
- This advancement facilitates the use of PM-HCF in precision metrology, gyroscopes, and laser delivery systems.

5.0K
The presence of a dielectric medium in a capacitor not only changes the voltage and capacitance but also affects the electric field. In general, dielectrics can be of two types: polar and nonpolar. In a polar dielectric, the positive and negative charges in the molecules are separated by a distance and hence have a permanent dipole moment. In contrast, no such charge separation exists in a nonpolar dielectric, however the nonpolar molecules get polarized in the presence of an external electric...

01:23Transmission Line Design Considerations
213
Aluminum has become the material of choice for overhead transmission lines, surpassing copper due to its abundance and cost-effectiveness. The most prevalent type is the aluminum conductor, steel-reinforced (ACSR), which combines aluminum strands around a steel core. Other variants include all-aluminum conductors (AAC), all-aluminum alloy conductors (AAAC), aluminum conductor alloy-reinforced (ACAR), and aluminum-clad steel conductors. Advanced designs, such as aluminum conductors with steel...

A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

01:01Group Polarization
35.4K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

1.7K
A coaxial cable consists of a central copper conductor used for transmitting signals, followed by an insulator shield, a metallic braided mesh that prevents signal interference, and a plastic layer that encases the entire assembly.
In the simplest form, a coaxial cable can be represented by two long hollow concentric cylinders in which the current flows in opposite directions. The magnetic field inside and outside the coaxial cable is determined by using Ampère's law. The magnetic...
