摘要：

We present a modeling study carried out to support the design of a novel, to our knowledge, kind of photonic-crystal fiber (PCF)-based sensor. This device, based on a PCF Bragg grating, detects the presence of selected single-stranded DNA molecules, hybridized to a biofilm in the air holes of the PCF, by measuring their interaction with the fiber modes. To model the system a method derived from the perturbation theory for Maxwell's equations has been used. This method has been fully characterized, and some of its properties are here pointed out.
