摘要： A Cu2O spherical assembly particle composition is composed of Cu2O spherical assembly particles, each of which is formed by agglomerating a plurality of Cu2O ultrafine particles that have an average diameter in the range from 1 to 100 nm and a standard deviation on the diameter in the range from 0 to 10%. The Cu2O spherical assembly particles have an average diameter in the range from 0.1 to 10 μm and a standard deviation on the diameter in the range from 0 to 40%. This Cu2O spherical assembly particle composition is composed of Cu2O assembly particles with excellent uniformity, so it shows excellent properties such as realizing a good electric conductivity during a curing process for wiring. Accordingly, the spherical Cu2O assembly particle composition may be usefully used as precursors for solar energy conversion, magnetic storage medium, catalyst, gas sensor, and copper wire formation.

摘要： Provided is an athermal external cavity laser (ECL), whose output optical power and output wavelength can be kept regular irrespective of temperature changes without using additional temperature controlling components. The ECL comprises: a semiconductor amplifier; an optical fiber comprising a core in which a Bragg grating is formed and a cladding surrounding the core; and a thermosetting polymer that fixes the optical fiber to a ferrule and has a negative thermooptical coefficient, wherein the thickness of the cladding surrounding the core in which the Bragg grating is formed is smaller than the portion of the cladding surrounding the portion of the core where the Bragg grating is not formed, and the thermosetting polymer the negative thermooptical coefficient surrounds the cladding. The ECL does not need additional temperature controlling components and thus can be manufactured compact and at low cost, and thus can be used as a light source of a dense wavelength division multiplexing (DWDM) system in designing economical WDM passive optical networks (PON).

摘要： In a Wavelength-Division-Multiplexed Passive Optical Network (WDM-PON) utilizing a conventional downstream optical signal reusing method, there is an inventory problem that different optical transmitter types need to be provided for the operation, management, replacement, etc. of a system. A WDM-PON system according to the present invention, includes: a seed light (SL) unit generating a seed light whose wavelength intervals and center wavelengths are adjusted using at least one seed light source; an optical line terminal (OLT) receiving the wavelength-multiplexed seed light from the seed light unit, transmitting a downstream optical signal to a subscriber of the WDM-PON, and receiving a upstream optical signal from the subscriber; and an optical network unit (ONU) receiving the downstream optical signal from the OLT, flattening and modulating the downstream optical signal with upstream data so that the downstream optical signal is reused for carrying upstream data. It is possible to improve the quality and reliability of downstream transmission by sufficiently increasing an extinction ratio, and improve the quality and reliability of upstream transmission by sufficiently flattening an input downstream optical signal in a semiconductor optical amplifier.
