An FC-type optoelectronic assembly is provided that has a threaded plastic body that is adapted to mate with a threaded sleeve of an FC plug by engaging the threaded sleeve the FC plug with the threaded body of the FC-type optoelectronic assembly. The threaded plastic body is transparent to an operational wavelength of the FC-type optoelectronic assembly and has an optical element integrally formed therein. A TO-can header is housed in the threaded plastic body. A miniature PCB may be used for mounting the electrical and optoelectronic components of the TO-can header assembly on the header of the TO-can header assembly.

An optical transmitter includes a transmitter optical subassembly (TOSA) having a transistor outline (TO) package, a flexible circuit, and at least one active electronic device mounted on the flexible circuit. The active electronic device includes circuitry for processing signals communicated to and from the TOSA.

A package for opto-electrical components, includes a casing having (1) a chamber and (2) at least one board or tile for carrying the opto-electrical components. The casing has an opening (shaped as a parallelogram) defining an optical feed-through path between the chamber and the outside of the casing. The casing includes ceramic material in the vicinity of the opening. An adapter associated with the opening has a substantially circular aperture to accept a fiber pigtail and/or a fiber optic connector.

Package for opto-electrical components

A package for opto-electrical components includes a casing having a chamber for at least one board or tile adapted to carry the opto-electrical components. The casing includes a set of electrical connections including at least one radio-frequency differential line between the chamber and the casing exterior.

A package for opto-electrical components includes a casing having a chamber, and an optical feed-through between the chamber and the casing exterior. At least one board or tile adapted to carry opto-electrical components is in the chamber. The board or tile creates a solid mechanical structure with the casing while providing electrical ohmic connections with a set of electrical connections on the casing. The board or tile is from of an assortment of boards or tiles of different types.

Optical pulses at a given repetition rate (f) are obtained by modulating an optical signal by means of a Mach-Zehnder modulator. The modulator is driven by means of a driving signal including, in addition to a sinusoidal component at a frequency (f/2) half the repetition rate (f) of the pulses, at least one odd harmonic of the sinusoidal component. Very short optical pulses can thus be generated without giving rise to undesired side effects such as ringing in pulse tails.

The signal to be controlled is sent along an optical fiber by a wavelength tunable laser whose emission wavelength may be varied as a function of a possible phase variation in the received signal with respect to a reference phase. At the receiving end of the fiber a control signal is generated by extracting a fraction of the power associated with the received signal and sending such fraction back towards the transmitting end, and at the transmitting end the phase of the fraction is compared with that of the original signal and the tunable laser is driven in such a way as to transmit a wavelength such that the clock information reaches the receiving end with the reference phase.

Optical demultiplexing system, wherein from an optical carrier modulated by a TDM data flow the wanted tributary is extracted as an optical signal. The system makes use of a semiconductor optical amplifier, whose gain is modulated due to saturation effect. The amplifier receives both the modulated optical carrier and one or a plurality of sampling optical carriers, with wavelengths different from that of the modulated carrier. One or a plurality of optical filters supply at the output the tributaries by extracting from the amplifier output the sampling carriers modulated by data signals.
