This is the 2010 Annual Review of Microsystem Research Center in the P & I Lab. (Precision and Intelligence Laboratory), Tokyo Institute of Technology at Suzukakedai Campus.
The opto-electronics field is meeting an evolutionary stage, i.e., multi-media networks require high speed and low cost lightwave infrastructures, and high speed data-communication is becoming extremely important for Gigabit local area networks. Also, the optical interconnect is penetrating into computers and electronics equipments.
The surface emitting (SE) laser or vertical cavity surface emitting laser (VCSEL) is opening up a new development of optoelectronics technical field by utilizing low power consumption and 2-D arrayed configuration. Its threshold has been reduced to micro-amperes and the power conversion efficiency is becoming ahead of any other semiconductor lasers.
We have been studying on surface emitting lasers in wide spectral ranges from blue to infrared for the purpose of generating various applications such as high density optical disk memories, high speed LANs, optical interconnects and optical parallel processing.
Photonic integration, based on surface emitting lasers and parallel microoptics, is becoming one of the important technologies, and 2-dimensional optical devices are expected to solve the bottleneck of photonic networks.
Our research activities can be summarized as follows;
  1. Surface emitting lasers in wide spectral ranges
  2. Integrated photonic micro-devices
  3. Optical micro-electro mechanical systems (MEMS) and devices
  4. Fine epitaxial growth and microfabrication processes
  5. Parallel microoptics
In the year of 2001, we concluded the COE (Center of Excellence) Program, "Ultra-Parallel Opto-electronics Project (UPOP)", which was supported by the Ministry of Education, Science, Culture and Sports (MESCS).
We wish to acknowledge Prof. Emeritus Yasuharu Suematsu, the former President of Tokyo Institute of Technology for his encouragement and support of our activities. This study was supported by the Grant-in-Aid of MESCS and several grants. We would also like to thank the cooperating companies for their support.
