| Outline of Final Research Achievements |
We proposed and demonstrated high speed VCSEL photonics using a coupled cavity structure functioning like optical equalization. The small signal analysis based on rate equations was carried out to be over 100GHz by increasing the number of cavities. A 850 nm-band transverse coupled-cavity VCSEL has shown a 3dB bandwidth over 29 GHz, and a single-mode VCSELs exhibits a 30 GHz bandwidth after resonance tuning and large signal modulation up to 48GHz. Energy power consumption can be below 100 fJ/bit. We achieved the lowest power consumption of below 70fJ/bit. We also demonstrated output over 1mW for modulator integrated devices.
