  • NRN097 - EDC-Mediated Oligonucleotide Immobilization on a Long Period Grating Optical Biosensor

    • Sensors and Devices, 
    • Modelling, 
    • Knowledge Transfer, 
    • Materials

    We present the development and simplification of label-free fiber optic biosensors based on immobilization of oligonucleotides on dual-peak long period gratings (dLPGs). This improvement is the result of a simplification of biofunctionalization methodology.

    • Materials

    Low-cost vertical-cavity surface-emitting laser (VCSEL) and semiconductor optical amplifier (SOA) have been explored experimentally in a setup with a fiber ring resonator to generate flat broadband chaos. The effect of the frequency detuning between the fiber grating frequency and the free-running VCSEL's frequency, and the bias current of the SOA on the bandwidth of chaos has been studied.
