It is with great sorrow that we mark the passing of our esteemed friend and colleague Jeffrey Hesler. As our long-time CTO he has been instrumental in all that we have accomplished as a company, as well as to the growth and vitality of the greater Terahertz community. Most of all we will miss his friendship and kindness. At this difficult time, we look forward to the future where we will strive to continue his mission and help build his legacy.
