A uniaxially oriented crystal based on 9,10-bis(2,2-di-p-tolylvinyl)anthracene (BDTVA) with an excellent waveguide and polarization performance has been prepared. The low loss coefficient (2.75 cm–1) and the high polarization contrast (0.72) may result from the uniaxially oriented packing and layer-by-layer molecular structure in the BDTVA crystal. Moreover, amplified spontaneous emission is observed from the BDTVA crystal with a low threshold of 265 μJ/cm2, and the gain coefficient is 52 cm–1 at the peak wavelength of 509 nm. These features indicate that the BDTVA crystal may be potentially applied in the field of optical waveguides and organic solid-state lasers.
