TL;DR: High quality imaging in the near (1.5 μm) and mid-IR regions using high refractive index polymeric lenses from these sulfur materials was demonstrated.

TL;DR: In this paper, the optimal dimensions for the silicon waveguide in an electro-optic (EO) polymer cladding-based silicon modulator were found for both 1550 nm and 1310 nm wavelengths.

TL;DR: A novel electro-optic polymer modulator design is demonstrated which shows a record low optical insertion loss of 5.7 dB at 1550 nm and employs new low loss passive sol-gel materials.

TL;DR: This paper overviews recent research in optical communications and focuses on the topics of modulation, switching, add-drop multiplexer, coding schemes, detection schemes, orthogonal frequency-division multiplexing, system analysis, cross-layer design, control and management, free space optics, and optics in data center networks.

TL;DR: In this paper, a silica/electro-optic (EO) polymer phase modulator is proposed for microwave radiation receiver with the use of a bowtie antenna, which shows a broadband response with a maximum at 5 GHz and a 3-dB-bandwidth of approximately 12 GHz.
