2、為硬件基質(zhì)的硅材料據(jù)有舉足輕重、不可替代的地位，人類社會已經(jīng)進(jìn)入硅器時(shí)代！周治平、王興軍教授 北京大學(xué)信息科學(xué)技術(shù)學(xué)院Research Topics Silicon Photonics and Microsystems Light Sources Modulators and Detectors Beam Splitters and Rotators Surface Plasmonic Devices Sub-wavelength Grating Devices Integrated Optical Sensors Photonic Crystal Devices Simulation and

3、 IntegrationWhat is Silicon Photonics?Chip size optical solutions emphasize on interaction between photons and electrons.Studies the principles and technologies of merging electronics and photonics into the silicon platform. It is considered a more efficient and lower cost optical solution.Why Silic

4、on Photonics? To meet the challenges in high-density data communications , real time sensing/detection, high-speed control/actuation, etc.Difficulty in Silicon PhotonicsSilicon has low absorption coefficient in optical communication wavelengths, therefore, good waveguide property. But,1. It is indir

5、ect bandgap material: light emission efficiency is very low;2. It has highly symmetric crystal structure, therefore, the linear EO effect is zero;3. It uses photons as information carriers: the connections and processing compatibility with ICs need a lots of work.硅基光電子技術(shù)的必然趨勢集成電路中的量子效應(yīng)，熱效應(yīng)，以及超長互連線的延

6、遲效應(yīng)成了高速集成電路的障礙電子芯片中需要光互連寬帶光通信及WDM網(wǎng)絡(luò)技術(shù)使通信行業(yè)得以飛速發(fā)展但利潤卻降到了最低點(diǎn)芯片上的光電集成有利于光通信的進(jìn) 步發(fā)展“Silicon Photonics” has been very frequently appeared in IEEE, OSA, SPIE conferences and publications publicationsMany countries and areas have started major programs focusing on Silicon PhotonicsDevelopment in Silicon Pho
