POET sampling 100G and 200G CWDM4 Optical Interposer-based engines from early July
POET Technologies Inc of Toronto, Ontario, Canada — a designer and developer of integrated optical engines, based on the POET Optical Interposer, for the optical communications, computing and sensing markets — says that samples of its 100G and 200G CWDM4 Optical Engines will be available from early July.
Powered by four flip-chipped 28G and 28G PAM4 CWDM (course wavelength division multiplexed) distributed feedback (DFB) lasers, the optical engines include an integrated athermal multiplexer and demultiplexer, 28G detectors, monitor photodiodes and bonding pads. Operating to MSA (multi-source agreement) standards for the QSFP28 module, the POET Optical Engines will be available in chip-sets for transmit only, receive only or in a combination transmit and receive single multi-chip engine less than 60mm square.
Fabricated on a high-resistivity 8” silicon wafer with low-loss, athermal waveguides, POET’s Optical Engines include passively aligned active devices and superior thermal management, it is claimed. These engines offer what is said to be best-in-class coupling efficiencies, including to fiber attach units, and operate over a range of 500m to 10km under ambient operating temperatures of 0°C to 70°C.
Based on the POET Optical Interposer platform, the 100G and 200G Optical Engines are fabricated entirely at wafer scale, offering cost and size advantages. All engines are fully tested and burned-in prior to shipment. Super Photonics Xiamen Co Ltd, POET’s joint venture with Sanan Integrated Circuit Co Ltd of Xiamen City, Fujian province, China, will be manufacturing the optical engines, with the capability to rapidly scale for customers with high-volume requirements.
POET will also soon be offering 400G DR4 and FR4 transmit and receive optical engines. Samples of the receive optical engine will be available in September. Samples of the transmit engine, based on high-power CW (continuous wave) lasers and silicon photonic modulators, will be available beginning in fourth-quarter 2021.
Live demonstrations of POET products are being conducted by the firm during the virtual Exhibition at the Optical Networking and Communication event (OFC 2021) on 7–11 June.
