Abstract
Optical signal processing is accomplished by an arrayed-waveguide grat ing multiplexer (AWG) provided with an optical semiconductor amplifier (OSA) in each loop-back optical path. The proposed configuration can easily realise three useful functions: amplification, modulation and d emodulation. Dynamic signal processing in the fabricated 1.55 mu m loo p-back type AWG multiplexer is successfully obtained and confirmed to operate in accordance with the design.
