Abstract

The current standard for communications system on satellites are high size, weight, and power (SWaP) RF transceivers, which is contrasted with the low SWaP solar arrays that implement III-V semiconductors for optimal solar collection. An alternative, low SWaP solution is to implement a hybrid photovoltaic (PV)/electroabsorptive modulator (EAM) coupled with a retroreflector and use free space optical communication over 1.55 μm rather than RF communication. A design which minimizes parasitic losses and optimizes contrast ratio and cutoff frequency in a 1 cm2 device is discussed.
