Monolithic Semiconductor Lasers with Dynamically Tunable Linear-to-Circular Polarization [PDF]
ACS Photonics, 2017 The ability to control the polarization state of emission from semiconductor lasers is essential for many applications in spectroscopy, imaging, and communications, inter alia, with monolithic integration approaches being extremely beneficial. Although manipulating the output polarization of radiation from a laser can be achieved through a number of ...

Linear and circular polarization of the cosmic background radiation
The Astrophysical Journal, 1983 New data which consist of continued measurements of the linear polarization of the cosmic background radiation as well as the first measurement of the circular polarization are examined. Eleven declinations have been surveyed for linear polarization and one declination for circular polarization, all at 9 mm wavelength. No evidence is found for either a

Linear-to-Circular Polarization Reflector With Transmission Band [PDF]
IEEE Transactions on Antennas and Propagation, 2014 A frequency selective surface (FSS) which can be utilized as a diplexer for circular polarization (CP) applications is proposed. The structure consists of two dipole-based FSS placed parallel to each other. The dipoles in one array are rotated by 90° with respect to those in the other.

The Polarized Emission of AGN at Millimeter Wavelengths as Seen by POLAMI
Galaxies, 2022 We review results from the POLAMI program, which monitors the polarization properties of 36 blazars at the IRAM 30 m telescope. We found that the variability of the degree of linear polarization is faster and of higher amplitude at 1 mm than at 3 mm and ...
