POET Technologies Inc. announced the Company has successfully demonstrated a high-frequency waveguide integrated PIN Photodiode targeting 100G and 400G data center applications. The achieved native bandwidth are more than capable of supporting the requirements of a 100G Receive Optical Engines (4 lane at 25Gb/s each), and they can be extended to support 200G/400G engines. Unlike more conventional top-entry PIN photodiodes, POET utilizes an evanescently-coupled twin waveguide structure with integrated spot-size converters that is compatible with its recently announced Optical Interposer Platform and is designed to operate in the wavelength range from 1310nm to 1550nm.
