Jack, I have never seen anywhere from the company that products will be ready in 'June'.

From the NR in April. "In February, POET’s DenseLight subsidiary demonstrated the newest generation of its Constellation Series of narrow linewidth laser (NLWL) solutions for Wind LIDAR and Distributed Acoustic Sensing applications. These NWL laser were specifically designed to meet the increasing requirement across multiple end markets for superior Relative Intensity Noise (RIN) performance and ultra-narrow linewidths. This new family of products simplifies the overall design process for OEMs, while also shortening development time and significantly accelerating time-to-market. The Company plans to make engineering samples available in the second quarter of 2017 and expects to begin commercial production in the second half of the year."

Second half of the year is July - December. I'm happy to get a calculator and diary out to help you work out what second half of the year is :). Happy to be proven wrong if you can highlight a June quote from the company.
