  • Publication number: 20260121748
    Abstract: 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.

  • Publication number: 20250202587
    Abstract: A co-packaged optical-electrical chip can include an application-specific integrated circuit (ASIC) and a plurality of optical modules, such as optical transceivers. The ASIC and each of the optical modules can exchange electrical signaling via integrated electrical paths. The ASIC can include Ethernet switch, error correction, bit-to-symbol mapping/demapping, and digital signal processing circuits to pre-compensate and post-compensate channel impairments (e.g., inter-channel/intra-channel impairments) in electrical and optical domains. The co-packaged inter-chip interface can be scaled to handle different data rates using spectral efficient signaling formats (e.g., QAM-64, PAM-8) without adding additional data lines to a given design and without significantly increasing the power consumption of the design.

  • Patent number: 12335668
    Abstract: 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.

  • Patent number: 11522616
    Abstract: A method includes applying, to a modulated digital signal, a forward error correction (FEC) including a low-density parity-check (LDPC) to produce a coded digital signal. Nyquist shaping is applied to the coded digital signal to generate a filtered digital signal. A representation of the filtered digital signal is transmitted in an optical communication channel via a dense wavelength division multiplexing (DWDM) scheme.
