We demonstrate a waveguide-integrated Ge/Si APD with 3dB bandwidth of 52.2GHz at gain of 3.8 and 45.8GHz at gain of 6. This device also shows a large dynamic range with responsivity changes 1.6-3.5A/W. This high-performance device is suitable for various 200Gb/s per lane applications.Show More
We report a waveguide Ge/Si APD with ultra-high 3dB-bandwidths: 56GHz with a 1310nm responsivity of 1.08A/W and 36GHz with a 1310nm responsivity of 6A/W, which, to our knowledge, are the best performance among all reported APD devices.Show More
Silicon photonics is considered as one of the promising technologies for high-speed optical fiber communications. Among various silicon photonic devices, germanium on silicon avalanche photodiodes (Ge/Si APDs) have attracted tremendous attention due to their the properties of high performance and low cost. The sensitivity of 10Gb/s APD reached -29.5dBm at 1550 nm with the bit error rate of 1 × 10-...Show More
We experimentally demonstrate, for the first time, link BERs under the KP4 FEC threshold at 42.5 Gbps over 550 m high bandwidth OM4 using single 850 nm VCSEL and at aggregated 212.5 Gbps over 300 m wideband multimode fiber using SWDM TOSAs from 850 to 940 nm, employing a newly developed PAM4 chipset and direct detection, with a novel Ge/Si APD or wideband PIN ROSA.Show More
Owing to the breakthrough of Ge/Si avalanche photodiode, we developed a cost effective 25G APD TO-can solution for various 100G applications including 100G-PON, 5G wireless, and data center applications with PAM4 and DMT modulations.Show More
Our germanium on silicon avalanche photodiodes (Ge/Si APDs) show a 1310nm sensitivity of -22.5dBm at 25.78Gb/s, which is, to our knowledge, the best sensitivity in reported 25Gb/s avalanche photodiodes.Show More
We review our recent development of germanium on silicon avalanche photodiodes (Ge/Si APDs). Our Ge/Si APDs, manufactured by a standard CMOS commercial foundry, satisfy the requirements of various optical communication systems from 10Gb/s to 25Gb/s.Show More
Our CMOS-foundry mass-produced Ge/Si optoelectronic devices have passed the high temperature accelerated aging test, THB test and HAST test, which demonstrate satisfactory reliability and promising potential for non-hermetic applications.Show More
We developed world first 25Gb/s normal incident germanium silicon avalanche photodiode (Ge/Si APD) in a CMOS commercial foundry. The vertically illuminated Ge/Si APDs have a large 3-dB bandwidth (>18GHz) at a high gain (M=8) which is suitable for 100GBASE-ER4 application.Show More
