Outline of Final Research Achievements

We performed new challenges for athermal and tunable surface emitting lasers based on MEMS structures and developed various VCSEL-based slow-light devices and their integrations, which enable size reduction and high-speed operations. We realized widely tunable athermal VCSELs with a tuning range of over 30nm. Also, we demonstrated VCSEL-based novel devices such as an ultra-compact slow-light switch, modulator and super-high resolution beam steering device, exhibiting a number of resolution points of over 1,000. In addition, we proposed and demonstrated a coupled cavity VCSEL and modulator-integrated VCSEL based on slow-light lateral integration, exhibiting high-speed operation beyond 30GHz with low power consumption. The achievement also includes a compact wavelength selective switch supporting ultra-high port account of over 180, which may open up new photonics integration scheme.
