Fundamental Research And Performance Analysis Of Photonic Crystal Microcavity

The times we are living is a semiconductor era in some sense. The emergence of semiconductor brought impact from daily life to high-tech revolutionary. Larg-Scale Integration, computers, infobahn, and so on with which even the students are familiar is brought by semiconductor. Almost all semiconductor devices are focusing on how to use and control electronic movement in which an electronic is the decision. Now semiconductor devices are in their peaks. The integration limit in the future can be seen which is decided by the electronic characteristics. But photonic has advantages electronics do not have: speed-up, no interaction. Therefore, photonic will act the leading role in the next generation of devices.Photonic crystals(PCs) is put forward in 1987 as a new concept and new material. One notable feature of this material is that itsmovement can be controlled if people want to. Because of its unique characteristics, high-performance optical devices which have new theories or can not be produced previously can now be produced using PCs. The Photonic crystal has important applications in optical communication, such as photonic crystal devices which is used to replace traditional electronic devices, the high speed of information communication is beyond imagination.Traditional production methods of resonant cavity is very difficult for the manufacture of the microcavity. Traditional metal resonant cavity has considerable depletion in lightwave bands. There are many optical depletion mechanisms, such as diffraction depletion, the transimission of a reflector, scattering of the medium in the cavity, non-life absorption and so on, so the quality factor(Q factor) is low.
