Widely tunable distributed-feedback lasers with chirped gratings
A quasicontinuous tuning range of 65 nm at 3.2 m was obtained for continuous wave, single-longitudinal-mode operation at 77 K of an optically pumped distributed-feedback laser with a chirped grating. Interferometric lithography with spherical wavefronts was used to fabricate a large-area chirped grating whose period varied continuously in the direction of the grating lines. Tuning was achieved ...

متن کاملEdge-enhanced imaging with polyvinyl alcohol/acrylamide photopolymer gratings.
We demonstrate edge-enhanced imaging produced by volume phase gratings recorded on a polyvinyl alcohol/acrylamide photopolymer. Bragg diffraction, exhibited by volume gratings, modifies the impulse response of the imaging system, facilitating spatial filtering operations with no need for a physical Fourier plane. We demonstrate that Kogelnik's coupled-wave theory can be used to calculate the tr...
متن کاملSubwavelength surface-relief gratings for stellar coronagraphy.
We present a new design of a phase mask coronagraph implemented with subwavelength diffractive optical elements consisting of optimized surface-relief gratings. Phase mask coronagraphy is a recent technique that seeks to accommodate both high dynamic and high angular resolution imaging of faint sources around bright astrophysical objects such as exoplanets orbiting their host stars. The origina...
متن کاملDistributed Feedback Lasers Based on Thiophene/Phenylene CoOligomer Single Crystals
Organic solid state lasers have attracted considerable attentions because they have the potential to be tunable, flexible, biocompatible, and easily integrated into plastic optoelectronics.[1–8] Optically pumped laser has been reported in a very broad range of conjugated polymers and oligomers. However, for the electrically pumped organic lasers, there still exist many challenging problems to b...
