Very interesting to see the big promo for the 1550nm ultra narrow line width laser which is used in the HIPPTM-SOE for FMCW LiDAR (Interrogator System Application) that was presented last year associated with automotive LIDAR  by Lam Yee Loy.

And to answer Baba's question. POET does not build switches they are building the optical engines for the QSFP form factor transceiver that plugs into the switch ports. So not the competition.
