Abstract
A component vital to the successful implementation of single-mode fiber signal processing and communications systems is an integrated inline Bragg cell that can function as a modulator, SSB frequency shifter. and tunable WDM tap. A number of reported devices go toward achieving this goal, the most efficient to date being the flexural-wave modulator in a dual-mode single-core (DMSC) fiber developed by Kim et al. In their device the LP mode is not appropriate for efficient pigtailing to a single-mode fiber. The dual-core (DC) device we have developed avoids these problems by permitting low-loss fusion splicing of a single-mode fiber to either core and having negligible intrinsic coupling. This is achieved by designing the DC to be phase velocity mismatched to such a degree that the NMs of the DC coupler are almost identical to the modes of each core in isolation.
