... Beyond the data rates of 1-2 GHz, the complex dynamics of the coupling of electrons and photons within the laser cavity cause undesirable frequency variations, known as chirps. In presence of chirp, the signal gets distorted as propagates on the optical fiber. For high data rates a better option wou ...

... Coupling efficiency between a SMF and a waveguide whose transverse intensity distributions are gaussian depends on the mismatch between their MFD. As the coupling efficiency is the overlap integral between the two field amplitudes, it is the higher when the two fields are the same and decreases with ...

Total Reflection
... A lesser-known aspect of total internal reflection is that the reflected light has an angle dependent phase shift between the reflected and incident light. Mathematically this means that the Fresnel reflection coefficient becomes a complex rather than a real number. This phase shift is polarizat ...
