Applied Optoelectronics 100Gbps per lambda PIN photodiodes

Applied Optoelectronics Inc (AOI) of Sugar Land, TX, USA – a designer and manufacturer of optical components, modules and equipment for fiber access networks in the Internet data-center, cable TV broadband, fiber-to-the-home (FTTH) and telecom markets – has announced the availability of 100Gbps per lambda PIN photodiodes (PD) for high-speed optical transceivers.

Designed for operation in the optical communication wavelength bands between 1270nm and 1610nm, the 100Gbps indium gallium arsenide (InGaAs) PIN photodiodes are front-side illuminated and feature a high-speed ground-signal-ground (GSG) electrical pad configuration. In addition to high bandwidth, the devices are also designed to have high responsivity, low capacitance, low dark current, and excellent reliability even in the most demanding application environments. The 100Gbps PIN PD with 15µm aperture can achieve receiver sensitivity of -9dBm optical modulation amplitude (OMA). Pairing this with AOI’s 100Gbps 4-level pulse amplitude modulation (PAM4) lasers, the 100Gbps PIN PD is suitable for applications such as 100G DR, 100G FR, 400G DR4 and 400G FR4 transceivers (used primarily by large data-center operators to interconnect switches within their data centers).

“The laser diode and the photodiode are the two critical active optical components in fiber-optic transceivers,” says Dr Jun Zheng, vice president of R&D. “With this new 100Gbps per lambda PIN PD, we are now able to manufacture both of these key components in our in-house fab, which enhances our vertical integration and allows us to better serve our 100G and 400G customers.”

The devices are available for sampling now, with volume production expected in second-quarter 2019.
