Abstract
Presented in this paper is an introduction of a fiber-type optical phased array antenna for free- space optical communications. Optical phased array antenna is a phased array antenna operated at optical frequency. The high speed beam steering, spatial power combining, and flexible beam forming characteristics of them will drastically improve the performance of future free-space optical communication systems. The system design of a fiber-type optical phased array which can steer an optical beam in 2-dimension is reviewed. Fundamental characteristics of the integrated optical beam forming network (BFN) are shown. The wide bandwidth response up to 924 MHz of optical phase shifters, which enables high speed beam steering, is highlighted. Radiation patterns demonstrate coherent spacial power combining.
