“…With the rapid development of the Internet, data centre and 5G technology, the communication data traffic grows exponentially and requires to continue improving communication capacity [1,2]. At present, optical communication is widely used in data centres, and the optical modules in data centres are developed from 10G/40G to 100G/400G or beyond [3][4][5][6][7]. And high-bandwidth optical modules require the perfectperformance optoelectronic device and the design of the package [8][9][10][11][12][13].…”

The microring modulator (MRM) is a small‐size and low‐power component, which is the potential for the next‐generation optical interconnection. By the theoretical analysis, increasing the electrical bandwidth, which is relevant to the cross section and the doping concentration of the doping region, is a better way to increase electro‐optical (EO) bandwidth. Therefore, a new doping profile of the PN depletion region with 4 doping concentration levels is introduced considering the electrical bandwidth. Based on the new doping profile, the MRM with the 160 μm length and the 0.33 and 0.2 μm coupling space are determined considering the trade‐off between the EO bandwidth, quality factor (Q), extinction ratio, area of MRM, and power consumption. Moreover, the MRM is characterised and is applied in a wavelength division multiplexing transmitter. By the measurement, the transmitter with the designed MRM could transmit PAM4 signal at 52 Gbps rate, which indicates the MRM could be potential for the 50 Gbps/ch optical interconnection.

“…Recent research has therefore focused on co-integrating silicon photonic devices with electronic components [7]. Various groups have shown either 2D/2.5D integration [8][9][10][11], 3D integration [12][13][14][15][16][17][18][19][20] or monolithic integration [21][22][23][24][25][26][27] to be possible.…”

As the reach of optical communications continues to shrink, photonics is moving from rack-to-rack datacom links to centimeter-scale in-computer applications (computercom) where different architectures are needed. Integrated optical microring resonators (MRRs) are emerging as an attractive choice for fulfilling the more stringent area and efficiency requirements: They offer scaling by wavelength division multiplexing (WDM) and high bandwidth densities. In this paper we present compact electro-optical transmit (TX) and receive (RX) macros for computercom monolithically integrated in 45nm CMOS. They operate with MRR modulators and photodetectors and include all necessary electronics and optics to enable optical links between on-chip data sources and sinks. A most compact implementation for thermal stabilization was enabled by sensing the optical device's bias currents in the driving electronics instead of using external operating point sensing optics. Using a field-effect transistor as heating element -as is possible in monolithic integration platforms -further reduces area and power necessary for thermal control. The TX macro is shown to work for data rates up to 16 Gb/s with a 5.5 dB extinction ratio (ER) and 2.4 dB insertion loss (IL). The RX macro demonstrates a sensitivity of 71 µApp at 12 Gb/s for a BER ≤ 10 -10 . An intra-chip link built with the macros achieves ≤ 2.35 pJ/b electrical efficiency and a BER ≤ 10 -10 at 10 Gb/s. Both macros are realized within 0.0073 mm 2 which amounts to 1.4 Tb/s/mm 2 bandwidth density per macro.
