Abstract:
A method for optical chirp-free optical polarization modulation includes dividing a data modulated optical signal into a first optical path and a second optical path, using a Mach-Zehnder intensity modulator in the first optical path for imparting a π phase difference between adjacent symbols of the data modulated optical signal in the first optical path, adjusting a delay and amplitude of symbols of the data modulated optical signal in the second path so that the symbols in the first path and the symbols in the second path are synchronized and have substantially equal power levels, and combining the first and second optical paths so that symbols from the first and second optical paths are in orthogonal polarizations.

Abstract:
It is the object of the invention to eliminate a limitation on the transmission distance of a WDM optical transmission system caused by wavelength dependencies of gains of optical amplification repeaters. The transmission characteristic of optical signal of the transmission system against the signal wavelength can be flatted by using plural kinds of the optical amplification repeaters with different gain peak wavelengths, and the longer transmission distance can be obtained.
Abstract:
In an optical amplifying repeater, an input signal light which is propagated through a first transmission optical fiber is divided by an optical divider into a plurality of signal lights. Each of the signal lights is amplified in a corresponding optical amplifier among a plurality of optical amplifiers. The signal lights thus amplified are combined in an optical coupler to supply a second transmission optical fiber with a combined signal light. At least one of the optical amplifiers are controlled in its amplification gain so that a level of the combined signal light is held to be a predetermined value.
Abstract:
A pen tip structure comprises (1) an elongated stem which defines a cylindrical outer surface and a flat end surface, the flat end surface including one or more grooves which extend from the cylindrical outer surface radially inwardly towards a center point thereof, (2) a tube positioned around the elongated stem, the tube including inwardly-extending protrusions that form at least one longitudinal ink flow channel along the cylindrical outer surface of the elongated stem, and an end portion which is located beyond the flat end surface of the elongated stem, the end portion providing a mouth, and (3) a rotatable member positioned between the noted mouth and the flat end surface of the elongated stem, the rotatable member having a surface portion which extends beyond the mouth for conveying ink to a receiving surface and an opposite surface portion for receiving ink supplied thereto by capillary action. The longitudinal ink flow channel(s) supply ink to the groove(s) in the flat end surface of the elongated stem, the ink being reliably supplied to the surface of the rotatable member under all writing conditions by capillary action.
Abstract:
Disclosed is a device advantageously usable for dental therapy and examination, which is an elongated bundle of axially extending fibers. The elongated bundle is tapered at one or both of its ends, and the fibers are bonded to each other in places along their lengths so that the fiber bundle is coherent and the fibers define capillary passageways therebetween.
