摘要：

A simple, flexible method of postfabrication positioning of resonance wavelengths of long-period cladding-mode-coupled gratings is proposed. This method is based on changing the outer fiber diameter. Reducing the diameter by etching the fiber in HF acid shifts the loss peaks to higher wavelengths. A shift as large as 130 nm after 5 min of HF etching was observed for our strongest grating peak, corresponding to the cladding mode HE(19). The experimental results are in excellent agreement with model calculations. (C) 1996 Optical Society of America.
