Total Internal Reflection Fluorescence Microscopy

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Background:

Optical nanowires and nanofibers are crucial components in modern photonics.
Understanding endface reflectivity (ER) is essential for efficient light coupling and device performance.

Purpose of the Study:

To investigate the endface reflectivities (ERs) of various optical nanowires.
To analyze the factors influencing ER in nanowires, particularly their diameter, refractive index, and guided light wavelength.

Main Methods:

Utilized three-dimensional finite-difference time-domain (3D FDTD) simulations.
Simulated ERs for free-standing and substrate-supported silica, tellurite, PMMA, and semiconductor nanowires/nanofibers.

Main Results:

Obtained typical ER values for diverse nanowire materials and configurations.
Found that nanowire ERs are generally lower than those in conventional waveguides like optical fibers, especially in single-mode operation.
Detailed the dependencies of ER on nanowire diameter, refractive index, and light wavelength.

Conclusions:

The study provides crucial insights into the ER characteristics of optical nanowires.
Results offer valuable references for designing and optimizing nanowire/nanofiber-based optical resonators and lasers.
Highlights the importance of considering ER for sub-wavelength diameter nanowires.
