POET TECHNOLOGIES COMPLETES OPTICAL INTERPOSER DEVELOPMENT PROJECT

Poet Technologies Inc. has released updates related to multiple recent developments across the company.

In January, Poet completed its proof-of-concept project with its existing North American-based networking customer. As previously announced, Poet received orders in 2018 from this customer to provide initial device prototypes of its optical interposer platform to systematically address specific integration requirements under a paid development program. At its annual general meeting in September, the company disclosed that it had successfully completed all but one of an eight-step project and that it expected to complete the final milestone by the end of 2019. Poet recently completed this final deliverable and is now engaged in follow-on discussions aimed at products to be designed, qualified and incorporated into the customer's product portfolio.
