Outline of Final Research Achievements |
This research is based on active-MMI, that was a phenomenon firstly found by us, and has attemted to investigate on longitudinal intereference. As a result, we could successfully achieved the following results; (1) Single wavelength emission with sufficient SMSR of around 40dB on CW operation without using grating (world first) and the mechanism, (2) First observation of photon-photon resonce by using longitudinal interference phenomenon, and high speed modulation based on the phenomena, successfully. We believe that these results contribute to open up a new window of novle laser diode technology for future high speed communication system.
