OZ posted a link recently to PICMagazine under which DL/POET are listed as corporate partners. I don’t think the description was fully digested by the forum:

POET Technologies

POET Technologies is a global provider of innovative photonics products and services. Proprietary embedded dielectric waveguides combined with component-level integration and packaging give POET’s line of ROSA, TOSA and TXRX optical engines an extraordinary cost and performance advantage over Silicon Photonics or conventional free-space optics. Initially serving the 100Gbps Ethernet and LAN WDM markets, the form-factor compliant designs are scalable to 200G and 400G. POET’s optical engines offer a compelling and sustainable competitive advantage to transceiver manufacturers and end-users.

POET manufactures and packages its optical engines in its own in-house wafer fabrication, assembly and test facilities located at its Singapore-based subsidiary, DenseLight Semiconductors. Recognized worldwide for its technological innovations in high performance semiconductor infrared superluminescent light sources and lasers, POET offers an extensive line of Narrow Line Width lasers, DFB and FP lasers, Superluminescent LEDs, ELEDs and programmable modules for applications in photonic sensing and data communications.
