| Outline of Final Research Achievements |
With aiming at extremely low-power consumption operation lasers for on-chip optical interconnects in future LSIs, semiconductor membrane distributed-feedback lasers which enable extremely low threshold current operation and high-speed operation have been investigated.
As the results, we theoretically clarified the capabilities of low-power consumption as well as high-speed modulation of the semiconductor menbrane lasers, and experimentally demonstated extremely low threshold current operation of semiconductor membrane distributed-feedback lasers and semiconductor membrane distributed-reflector lasers which have better performance in output efficiency. Moreover, by integrating semiconductor membrane photo-detector with the semiconductor membrane distributed-feedback laser via optical waveguide, we demonstrated, for the first time, a semiconductor membrane photonic-integrated-circuit (MPIC).
