Waveguide fabrication and high-speed in-line intensity modulation in 4- N,N-4'-dimethylamino-4'-N'-methyl-stilbazolium tosylate

摘要: We report the formation of thin-film waveguides organic crystals by precision optical polishing and fabrication an electro-optic intensity modulation device based on a waveguide N,N-4′-dimethylamino-4′-N′-methyl-stilbazolium tosylate (DAST®) as overlay side-polished fiber (SPF). Successful single-crystal DAST® with thicknesses in 20–25 μm range have been produced. The were investigated via evanescent coupling technique using fibers rather than traditional end-firing methods. Surface quality is believed to sufficient for low-loss propagation. Electrodes added SPF/DAST® architecture observed out 18 GHz. frequency response extend beyond 100 GHz under optimum conditions.
