A photonic crystal (PC) device including one or more resonant optical structures defined by the photonic crystal structure is affixed to the end face of an optical fiber. The PC device is fabricated on a separate substrate, and then affixed to the fiber end face.

The tabs can be designed to break during transfer to the fiber, thereby facilitating transfer. Registration marks and / or the use of device templates having the same diameter as the fiber can be used to provide lateral alignment of the fiber to the resonant optical structures. Such alignment may be needed to provide optical coupling between the fiber and the resonant optical structures.
