20130011134 | OPTICAL COMMUNICATION DEVICE - An optical communication device includes a transmitter module and a receiver module. The transmitter module includes a two laser sources, two optical modulators optically coupled to the two light sources, respectively, and an optical coupler, a semiconductor optical amplifier, an optical coupler, four optical band-pass filters or a demultiplexer, and an optical multiplexer optically coupled in series. The laser beams emitted from the two laser sources are converted into four laser beams having different frequencies due to a four-wave mixing effect occurring in the semiconductor optical amplifier. The receiver module includes a demultiplexer and four photoelectric conversion elements to receive the four laser beams respectively and convert them to electrical signals. | 01-10-2013 |
20130129361 | OPTICAL TRANSMITTER MODULE AND TRANSMITTING METHOD - An optical transmitter module includes at least one light source, at least one optical modulator aligned to the at least one light source one by one, a first light interleaver, and at least one optical fiber. Each light source emits a light wave with a particular wavelength. Each optical modulator modulates the light wave of the corresponding light source, to form a central light wave having the particular wavelength and a number of secondary light waves having secondary wavelengths. The first light interleaver separates the secondary light waves from the central light wave. The at least one optical fiber transmits the secondary light waves. | 05-23-2013 |
20130148979 | OPTICAL TRANSCEIVER DEVICE - An optical transceiver device includes a transmitter, a first and a second optical circulators and a receiver. The transmitter transmits a light signal uploaded with an electrical signal. The first and second optical circulators each include three ports. The second port of the second optical circulator is configured for transmitting the light signal circulated via the first and second ports of the first optical circulator and the first port of the second optical circulator, and the third port of the second optical circulator is configured for receiving an incoming light signal. The receiver receives the incoming light signal circulated back via the first port of the second optical circulator, and the second and third ports of the first optical circulator and converts the incoming light signal to be an electrical signal. | 06-13-2013 |
20130170812 | OPTICAL FIBER POSITIONING STRUCTURE - An optical fiber positioning structure includes a first positioning member and a pair of second positioning members. The first positioning member includes a columnar shaped main body and a pair of latching portions extending from opposite side of the main body toward a same direction. Each second positioning member is columnar shaped, and the pair of second positioning members are clamped between the pair of latching potions and located below the first positioning member, such that a positioning space is bound by the pair of second positioning members and the main body for positioning an optical fiber. | 07-04-2013 |
20130170835 | OPTICAL TRANSMITTER DEVICE - An optical transmitter device includes a laser source, a driving circuit, and an optical modulator. The driving circuit is connected to the laser source. The driving circuit includes a thermistor configured for compensating the temperature variation of the laser source to stabilize the frequency of a laser beam output from the laser source. The optical modulator is configured for modulating the laser beam to form a plurality of second laser beams which have different frequencies. | 07-04-2013 |
20130230288 | OPTICAL FIBER - An optical fiber for use with a light source is illustrated. The optical fiber includes a main body with a cylindrical lateral surface and an end. The end includes an end surface substantially perpendicular to an axis of the main body and a convex connecting surface between the lateral surface and the end surface, thereby increasing incident angles of the light rays that refracted into the main body through the connecting surface. | 09-05-2013 |
20130272654 | MULTI-DIRECTIONAL OPTICAL CONNECTOR - A multi-directional optical connector includes a main body and pairs of lenses arranged on the main body. The main body and the lenses are made of transparent material. The lenses in each pair are coaxial with each other. Different pairs of lenses are arranged along different directions. | 10-17-2013 |
20130312229 | POSITIONING FIXTURE - A positioning fixture includes a clamping member, a supporting member, and a magnet. The clamping member includes a base body and an end portion protruding from the base body. The supporting member includes a main body and at least one protruding portion protruding from the main body towards the clamping member. The main body includes a mounting surface adjacent to the protruding portion. The main body defines a receiving groove at the mounting surface. The protruding portion engages with the end portion. The magnet is mounted on at least one of the supporting member and the clamping member, and at least another one of the supporting member and the clamping member is made of magnetic material. The optical component receives in the receiving groove, and the magnet provides a clamping force to clamp the optical component by using the supporting member and the clamping member. | 11-28-2013 |
