Highly sensitive refractometer with photonic crystal fiber long-period grating
Lars Rindorf, Ole Bang
We present highly sensitive refractometers based on a long-period grating in a large mode area PCF. The maximum sensitivity is 1500 nm/RIU at a refractive index of 1.33, the highes…
Sensitivity of photonic crystal fiber grating sensors: biosensing, refractive index, strain, and temperature sensing
Lars Rindorf, Ole Bang
We study the sensitivity of fiber grating sensors in the applications of strain, temperature, internal label-free biosensing, and internal refractive index sensing. It is shown tha…
Calculation of optical-waveguide grating characteristics using Green's functions and the Dyson's equation
Lars Rindorf, Niels Asger Mortensen
We present a method for calculating the transmission spectra, dispersion, and time delay characteristics of optical-waveguide gratings based on Green's functions and Dyson's equati…
Non-perturbative approach to high-index-contrast variations in electromagnetic systems
Lars Rindorf, Niels Asger Mortensen
We present a method that formally calculates \emph{exact} frequency shifts of an electromagnetic field for arbitrary changes in the refractive index. The possible refractive index…
