Monolithic CMOS photonics seeks to minimize total transceiver cost by simplifying packaging, design and test. Here we examine 25 Gb/s applications in the context of integrated transistor performance and demonstrate a 4λ×25 Gb/s reference design.
A manufacturable platform of CMOS, RF and opto-electronic devices fully PDK enabled to demonstrate a 4×25 Gb/s reference design is presented. With self-aligned fiber attach, this technology enables low-cost O-band data-com transceivers. In addition, this technology can offer enhanced performance and yield in hybrid-assembly for applications at 25 Gbaud and beyond.
We present the electrical characteristics of the first 90nm SiGe BiCMOS technology developed for production in IBM's large volume 200mm fabrication line. The technology features 300 GHz fT and 360 GHz fMAX high performance SiGe HBTs, 135 GHz fT and 2.5V BVCEO medium breakdown SiGe HBTs, 90nm Low Power RF CMOS, and a full suite of passive devices. A design kit supports custom and analog designs and...
We present a 20 Gb/s monolithically integrated transmitter with stacked CMOS driver and periodic-loaded PN-junction Mach-Zehnder modulator fabricated in IBM's sub-100nm technology node. Transmitter extinction ratios of 10 dB at 20 Gb/s are demonstrated.
