	1	Influences on the bandwidth at the drop port of the add/drop filter using a fiber grating coupler by uniform and linearly chirped fiber Bragg grating显示文摘Writing a fiber Bragg grating(FBG) in an optical fiber coupler is a very effective way to implement an optical add/drop filter(OADF).In order to analyze the influences on the bandwidth at the drop port of the OADF using fiber grating-assisted mismatched coupler,a uniform FBG and a linearly chirped FBG were written on the coupler,and two different OADFs were fabricated.The fiber grating is written in a 2×2 mismatched coupler,which is fused and tapered with a standard single mode fiber(SMF) and a high germanium doped photosensitive fiber,by using a 248 nm ultraviolet laser.For the OADF using the uniform FBG,the 3 dB and 20 dB bandwidths are 0.1 nm and 0.3 nm,respectively;for the OADF using the linear chirped FBG,the 3 dB and 20 dB bandwidths are 0.8 nm and 2 nm,respectively.The experimental results meet the theoretical analysis well.The bandwidth at the drop port of the device can be adjusted by adjusting the chirped coefficient of the linearly chirped FBG.
