I agree this whole article is a Poet plug. Couple quotes I really liked.

Solutions are on the horizon to make these devices even smarter. Two to look for include chip-scale integration of spectrometers — instruments that measure and analyze the movement of light — for mobile devices and miniature 3D sensing and imaging solutions for robotic surgery applications.

And

A 400G DML-enabled product, which could be introduced to the industry this year, would act like a slingshot and propel innovation in a number of sectors.

As photonics plays a larger role in our lives, the excitement around the industry builds. In 2022, it should have an unprecedented commercial impact, signaling even greater growth in the years ahead.
