Abstract :
We demonstrate a new method for fabricating tunable long-period fiber grating by bonding a cladding etched fiber to a corrugated silicon fixture. The long-period grating is formed by a built-in periodic sheer strain on the fiber/fixture interface. Loss tuning is achieved by varying the temperature of the fixture. Dynamic tuning range as large as 20 dB is obtained at the resonance wavelength over a temperature range from 25/spl deg/C to 245/spl deg/C.
