Kerr effect in a passive optical ring-resonator gyroscope using a hollow-core photonic-band fiber

Abstract

Optical Kerr effect in the passive ring-resonator optical fiber gyroscope (PORG) made from hollow-core photonic band-gap (PBG) fiber is analyzed theoretically using a simple optical field overlap method, comparing it with the passive ring-resonator optical fiber gyroscope made from conventional single mode fiber (SMF). The theoretical evidence show that optical Kerr effect induced rotation rate shift in PORG made from hollow-core PBG fiber should be reduced by 1~2 orders at different ring resonator length when the optical source spectral width is fixed.
