Phase-matched polarization coupling in high-birefringence fibers through the optical Kerr effect
Optics Letters
|October 2, 2009
Abstract:
We describe the use of the optical Kerr effect in a simple and novel way to write a transient polarization coupler in high-birefringence fiber. A conversion efficiency of as much as 0.4% is demonstrated, with a coupling bandwidth of approximately 0.4 nm. The method is fast and independent of any thermal drift. Potential applications include real-time tuning in wavelength-division demultiplexers and wavelength selection in optical spectrum analyzers.

01:01Group Polarization
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.

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
