    摘要: A method of deploying a passive optical combiner that is a broad bandwidth spectral wavelength combiner for combining the outputs from multiples transmitter photonic integrated circuit (TxPIC) chips and, thereafter, the amplification of the combined channel signals with a booster optical amplifier couple between the passive optical combiner and the fiber transmission link. The booster optical amplifier may be a rear earth fiber amplifier, such as an erbium doped fiber amplifier (EDFA), or one or more semiconductor optical amplifiers (SOAs) on one or more semiconductor chips. Such a combination of optical components simplifies the design of individual TxPICs and other such optical communication PICs, which has to take into consideration the nonlinear effects of difficult, high loss single mode fiber (SMF) links or other fiber-type links by allowing a higher power per channel to be achieved compared to the case where channel amplification is attempted directly on the TxPIC chip through the deployment of on-chip optical amplifiers, such as semiconductor optical amplifiers (SOAs), integrated in locations following the electro-optic (EO) modulators, if not integrated also at other locations on the same chip.

    摘要: An optical communication module comprises a plurality of monolithic semiconductor transmitter photonic integrated circuit (TxPIC) chips each having a plurality of optical signal channels approximating wavelengths on a standardized grid. Each of the channels comprises a laser source optically coupled to an electro-optic modulator. The outputs of the electro-optic modulators are coupled to inputs of an optical combiner integrated on each of the chips for combining the inputs to form a combined signal output from the chip. A second optical combiner combines the combined signal outputs from the TxPICs to form a combined optical signal group output. A booster optical amplifier is optically coupled to the second optical combiner to receive and amplify the combined optical signal group output from the second optical combiner.

    摘要: An optical transmission network includes an optical transmitter photonic integrated circuit (TxPIC) chip, utilized in an optical transmitter and has a plurality of monolithic modulated sources integrated for multiple signal channels on the same semiconductor chip is provided with channel equalization at the optical receiver side of the network that permits one or more such integrated modulated sources in the TxPIC chip to be out of specification thereby increasing the chip yield and reducing manufacturing costs in the deployment of such TxPIC chips. FEC error counts at the FEC decoder on the optical receiver side of the network includes counters that accumulate a plurality of bit pattern-dependent error counts based on different N-bit patterns in the received data bit stream. The accumulated counts of different N-bit patterns are utilized to provide for corrections to threshold and phase relative to the bit eye pattern as well as provided for weight coefficients for the optical receiver equalization system. The deployment of this type of equalization in a digital OEO REGEN network substantially reduces, if not eliminates, the need for dispersion compensating fiber (DCF) or EDFAs in an optical link of the network and enhances the optical receiver tolerance to chromatic dispersion (CD) so that an increase in chip yield is realized for TxPIC chips not operating with acceptable operational parameters, particularly with a desired frequency chirp parameter relative to at least one of the TxPIC modulated sources.
