Abstract

An in-fiber mode converter comprises fiber portions (10) constituting an input microlens, a fiber portion (20) constituting a phase shifting region adapted to convert a propagation mode of an optical signal into another propagation mode, and fiber portions (30) constituting an output microlens. The fiber portions are spliced, the converter is compact and losses are minimized relative to mode conversion in free space.
