    摘要： A sourceless co-packaged optical-electrical chip can include a plurality of different optical transceivers, each of which can transmit to an external destination or internal components. Each of the transceivers can be configured for a different modulation format, such as different pulse amplitude, phase shift key, and quadrature amplitude modulation formats. Different light sources provide light for processing by the transceivers, where the light source and transceivers can be configured for different applications (e.g., different distances) and data rates. An optical coupler can combine the light for the different transceivers for input into the sourceless co-packaged optical-electrical chip via a polarization maintaining media (e.g., polarization maintaining few mode fiber and polarization maintaining single mode fiber), where another coupler operates in splitting mode to separate the different channels of light for the different transceivers according to different co-packaged configurations.

    摘要： In some embodiments, an apparatus includes a quadrature amplitude modulation (QAM) optical modulator which includes a first phase modulator (PM), a second PM, a tunable optical coupler (TOC), and an optical combiner (OC). The TOC is configured to split a light wave at an adjustable power splitting ratio to produce a first split light wave and a second split light wave. The first PM is configured to modulate the first split light wave in response to a first multi-level electrical signal to produce a first modulated light wave. The second PM is configured to modulate the second split light wave in response to a second multi-level electrical signal to produce a second modulated light wave. The OC is then configured to combine the first modulated light wave and the second modulated light wave to generate a QAM optical signal.

    摘要： An optical device may include a modulator. The modulator may receive an optical signal. The modulator may modulate the optical signal to include a first channel and a second channel. The modulator may modulate the optical signal based on a training pattern associated with detecting a skew. The modulator may cause the first channel to interfere with the second channel. The modulator may perform a power measurement on the first channel and the second channel. The modulator may determine the skew based on the power measurement and the training pattern. The modulator may time delay the first channel or the second channel to align the skew based on the skew.

    摘要： An optical transmitter can generate probabilistically shaped quadrature amplitude modulation (PS-QAM) signaling for transmission over a fiber to a destination without optical amplification. The single fiber can transmit the PS-QAM signaling using dense wavelength division multiplexing having a relatively large number of channels that are closely spaced. A coherent receiver can receive the PS-QAM signaling for decoding without implementing chromatic dispersion compensation.
