Microstructured and Photonic Bandgap Fibers for Applications in the Resonant Bio- and Chemical Sensors

Figure 1

Operational principles and schematics of the two types of the resonant optical sensors. (a) Analyte-filled hollow photonic bandgap fiber-based sensor. Transmission loss through such a sensor is very sensitive to the values of both the real and imaginary parts of the analyte refractive index. (b) Sensor operating near the phase matching point of a core-guided-mode and a second mode featuring large overlap with the analyte region. In the case of a phase matching with a plasmon mode, propagation loss of a core-guided-mode is strongly dependent on the real part of the analyte refractive index.
