ABSTRACT : Based on the general circuit model of inter-phase power controller, the basic relationship of steady-state voltage of IPC is analyzed in this paper. Consequently a new concept is proposed to describe the basic feasible region of steady-state voltage of tuned IPC and its basic forms is defined under the conditions of tuned parameters. On the basis of aforementioned work, the respective regions in case of equivalent load in receiving end, susceptance of inductor and capacitor and parameters of phase shifter meeting the requirements of basic feasible region of voltage is mainly analyzed. Finally, the differences of feasible region of various TIPC with simulations are given.

Analytical formulae are presented for the first time to describe the shift in the resonance wavelength of LPG in response to etching of the fiber cladding or a change in the external refractive index. The accuracy of the formula is confirmed by comparision with numerical simulations and experimental results. We demonstrated that the resonance wavelengths of an etched LPG are more sensitive refractive index than those of an unetched grating. The bending properties of long period fiber grating written in different type fiber are studied experimentally. The transmission peaks and the central wavelength of LPG change with the bending of the fiber. A new peak appears at the shorter wavelength when the fiber is being bent. The changes of the peaks are different for different photosensitive fiber. Those properties have broad application foreground in fiber sensors and tunable filters.
