摘要：

The efficiency enhancement of an acoustooptic tunable filter on cladding etched single-mode fiber (SAU) is investigated experimentally. When the fiber diameter is etched down to 30 mum, the acoustooptic coupling efficiency from the LP01 core mode to the LP11 cladding mode was increased by an order of magnitude, and the RF power consumption was reduced by two orders of magnitude. A highly efficient 8-cm-long 25-mum-thick AOTF on cladding etched SMF with an insertion loss of <0.2 dB, and RF power as low as 1.1 mW was demonstrated.
