“…Furthermore, we recently developed other key technologies to enhance the aggregated bandwidth using the silicon photonics technologies. In terms of power efficiencies of the transmitter circuits, 4.99 mW/Gbps was high compared to other reported values which are listed in a previous paper [14]. To reduce the transmitter circuit power and realize higher data rates, we developed a novel low power silicon photonics four level pulse-amplitude modulation PAM 4 modulator [15].…”

“…The polarization dependent loss and operating window deviation for the device were estimated to be <1.0 dB and <0.4 nm, respectively. Monolithically integrating high-speed Ge-based photodetectors and TIA [14] with the DMZI-DeMUX arrays allowed for the detection of WDM optical signals with an arbitrary SOP through CMOS electronic circuitry.…”

We report our recent progress in silicon photonics integrated device technology targeting on-chip-level large-capacity optical interconnect applications. To realize high-capacity data transmission, we successfully developed on-package-type silicon photonics integrated transceivers and demonstrated simultaneous 400 Gbps operation. 56 Gbps pulse-amplitude-modulation (PAM) 4 and wavelength-divisionmultiplexing technologies were also introduced to enhance the transmission capacity.

“…C-band silicon RM-based photonic TXs have been presented so far as compact footprint and low-energy modules for WDM operation with up to 4 × 20 Gb/s [5] and 4 × 25 Gb/s [6] transmission capabilities, reaching even aggregate data rates up to 4 × 40 Gb/s [7] and 8 × 40 Gb/s [8] when employing 4-element and 8-element RM arrays, respectively. At the same time, C-band MZM structures have also been shown in impressive silicon photonic WDM TX prototypes allowing for transmission capabilities of up to 8 × 25 Gb/s [9] and 16 × 25 Gb/s [10], respectively, while C-band GeSi EAMs have also been incorporated in WDM TX configurations with 4 × 28 Gb/s modulation capabilities [11].…”

Today, the datacenter ecosystems are fueling the demand for novel transmitter (TX) technologies complying with the off-board, on-board, and chip-to-chip computing needs. This has set a new class of requirements for the TX infrastructure that should now offer multiple credentials, namely: high-speed, O-band operation for avoiding dispersion compensation in long distances, wavelength-division multiplexing (WDM) capabilities for higher throughput and multicasting/broadcasting support, and tight copackaging with low-power electronics. Silicon (Si) photonic TXs have been extensively studied toward high-speed and WDM TX engines targeting mainly C-band. Only a limited number of Si-Pho O-band TXs have been reported, however with ≤32 Gb/s/channel line-rate capabilities and with a WDM portfolio that has not been fully explored yet. In this paper, we introduce a novel silicon photonic high-speed O-band TX hardware platform that can meet the current datacom and computercom interconnect requirements. We demonstrate a ring modulator (RM) based four-channel WDM TX at 4 × 40 Gb/s non-return-to-zero (NRZ) operation that supports wavelength parallelism in unicast operation but can also pave the way toward WDM TX engines for the post-100 GbE TX era. Moreover, we present a broadband Si Mach-Zehnder modulator employed in a WDM modulation scheme of 2 × 25 Gb/s NRZ signals and demonstrate multicasting when combined with a 8 × 8 passive arrayed waveguide grating router (AWGR) wavelength router, addressing the broadcasting needs of traffic usually encountered in cache-coherent multisocket settings. Finally, we further demonstrate the tight synergy of O-band Si-RM modulators with high-speed CMOS electronics, presenting an RM-based TX assembly prototype employing a fully depleted silicon-on-insulator CMOS driver, delivering 50-Gb/s NRZ operation.
