Abstract:
We compare nonlinear impairments in phase-modulated transmission with and without polarization multiplexing. Using an analytic approach that enabled us to accurately predict the Q factor at the receiver, we show that, without polarization multiplexing, the differential receiver is insensitive to two-pulse cross phase modulation, whereas with polarization multiplexing two-pulse interaction between cross-polarized components causes significant performance degradation.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
