摘要
根据锥形光纤与平面环型微腔耦合原理,使用L-Edit版图设计软件设计并优化了锥形光波导与微腔耦合系统。利用MEMS工艺对SOI圆晶片进行加工,从而实现了锥形光波导与跑道型以及环型光波导微腔的集成。其中,光波导以及微腔通过ICP刻蚀顶层硅而成,矩形槽通过RIE刻蚀衬底硅而成。光波导两侧的矩形凹槽可方便光纤接入以及对出射光的探测,从而提高了光波导微腔耦合系统的稳定性。
Taper optical waveguide and microcavity coupling system based on the taper-fiber and planar microring cavity coupling theory was designed and optimized by L-Edit layout software.And integrated taper-waveguide and the runway and ring-type optical waveguide microcavity coupling systems were processed by MEMS technology on SOI wafer.Among them,the waveguide and the microcavity were formed by ICP etching the device layer silicon and rectangular grooves were formed by RIE etching the silicon substrate.Rectangular grooves on both sides of the waveguide provided an easy access for fiber and to detection of emitting light,thereby enhanced the stability of the optical waveguide microcavity coupling system.
