Tunable circularly polarized lasing emission in reflection distributed feedback dye lasers.
A tunable circularly polarized distributed feedback (DFB) laser based on reflection grating configuration was realized in a solution of 4- (dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM) doped methanol. Chiral photonic DFB structures with tunable photonic bandgap were generated by controlling the state of polarization of the two interfering pump beams. The dual-peak lasing ...
متن کاملSingle mode optofluidic distributed feedback dye laser.
Single frequency lasing from organic dye solutions on a monolithic poly(dimethylsiloxane) (PDMS) elastomer chip is demonstrated. The laser cavity consists of a single mode liquid core/PDMS cladding channel waveguide and a phase shifted 15th order distributed feedback (DFB) structure. A 1mM solution of Rhodamine 6G in a methanol and ethylene glycol mixture was used as the gain medium. Using 6 na...

متن کاملSelf-injected semiconductor distributed feedback lasers for frequency chirp stabilization.
It is well known that semiconductor distributed feedback lasers (DFB) are key devices for optical communications. However direct modulation applications are limited by the frequency chirp induced by current modulation. We demonstrate that a proper external control laser operation leads to chirp-to-power ratio (CPR) stabilization over a wide range of modulation frequencies as compared to the fre...
متن کاملProposed distributed feedback crystal cavities for x-ray lasers.
The strong interest in the coherent generation and guiding of x rays is well known. Many papers have recently appeared treating different concepts of stimulated x-ray emissions, 1-3 and x-ray guiding in thin films was achieved. 4 Crystals were suggested as end reflectors to generate feedback.' Here we suggest a different type of cavity using zeolite crystals that would guide the emitted x-rays ...
