Abstract :
The author\´s group has been trying to establish fundamental technologies necessary for "digital photonics," by realizing optically-controlled digital photonic devices and circuits based on artificial optical properties of semiconductors, including digital wavelength converters, optical 3R repeaters, optical logic gates, optical dynamic memories, and integrated optical isolators. In this paper, we introduce two examples of such semiconductor photonic devices developed recently in our laboratory as well as a novel epitaxial technologies for fabricating such devices, namely, an SOA / phase-shifter-integrated MZI all-optical switch circuit and an all-optical flip-flop for optical packet switching.
