How Do Optic Fibers Minimize Interference While Transmitting Information?

AI Thread Summary
Optic fibers transmit information by utilizing light, with the speed of light remaining constant regardless of wavelength, ensuring that the signal maintains its modulation throughout the transmission. While different wavelengths can travel through the core, interference is minimized due to the design of the fibers. Dispersion is a potential issue in multi-mode fibers, but it is managed to ensure that signals remain clear and understandable at the receiver. Overall, the technology effectively reduces interference, allowing for reliable data transmission. This enables high-speed communication with minimal signal degradation.

In optic fibers the how do v transmitt the information? will not there be interference of light as different wavelength of light travel in core?
 
Science news on Phys.org
The speed that light travels is independent of the wavelength. So the signal at any point in the cable is in the same state, or modulation, as it was at transmission.

Not quite -- dispersion can be a design issue in multi-mode fibers:

Ok I see. Though it is kept to a minimum so that the signal is still understandable at the receiver.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
