Switching between transverse electric (TE) and transverse magnetic (TM) polarization states in the output from a semiconductor laser is experimentally obtained through injection locking from an external TM polarized radiation. Switching, which is connected to the loss reduction of the TM modes caused by the injection-locking mechanism, is faster than a few nanoseconds, the resolution limit of our apparatus.

    In this letter, we propose a simple configuration that is capable of rotating a linear polarization state of light by a certain angle for a wide range of wavelengths. The device consists of three liquid-crystal cells: two homogeneous cells and one twisted nematic (TN) cell. It is well known that...

    We prove in this paper that any four-dimensional symplectic manifold is essentially made of finitely many symplectic ellipsoids. The key tool is a singular analog of Donaldson’s symplectic hypersurfaces in irrational symplectic manifolds.

    Monitoring of precipitation using high-frequency radar systems, such as the X band, is becoming increasingly popular because of their lower cost compared to their S-band counterpart. However, at higher frequencies, such as the X band, the precipitation-induced attenuation is significant, and...
