2011 -- The Highland Technology PH200 is the first product in the 'PH' series of extreme-performance photonic
instruments. The PH200 Nanowatt Photoreceiver, designed in collaboration with Phil Hobbs, is a free-space
optical/electrical converter that provides near shot noise performance in a rugged, compact package. The
unique photon feedback architecture delivers a bandwidth greater than 1 MHz, with an unprecedented combination
of linearity, bandwidth, and dynamic range for 10nA to 100μA photodiode signals.
