Abstract
A microbend-induced fiber grating is formed from a section of optical fiber configured to exhibit 'splitting' between the resonant wavelengths supported by the TE and TM components of the LP.sub.1m mode and the resonant wavelength supported by the odd/even HE.sub.2m components of the LP.sub.1m mode. Since only the TE and TM components are polarization dependent, by splitting and shifting the resonant wavelengths for these modes away from a system-desired wavelength(s) supported by the odd/even HE modes, a polarization insensitive microbend-induced fiber grating can be formed. A fiber core configuration including a central core region, trench and ring is formed to exhibit a large radial gradient in core refractive index profile, with a significantly steep transition between the ring index and the trench index, to provide the desired splitting between the (undesired, polarization sensitive) TE/TM modes and the HE mode.
