<P> The laser action was firstly demonstrated using 1-cyano-trans-1,2-bis-(4'-methylbiphenyl)ethylene (CN-MBE), that enhances its fluorescence from organic nanoparticle. The CN-MBE is not fluorescent and has enhanced fluorescence in aggregated nanoparticle state. CN-MBE doped PMMA film showed fluorescence over 400 ∼ 600 nm and spectral narrowed emission at 430 nm under pumping with a nanosecond pulsed laser at wavelength of 355 nm. CN-MBE:PMMA DFB laser waveguides were successfully fabricated, and lasing wavelength was over 430 to 490 nm. CN-MBE:PMMA DFB lasers showed laser threshold of 73 µJ/cm2 at the waveguide size of 15 mm × 100 µm × 5 µm. The output spectra had bandwidth as narrow as 60 pm FWHM, and suppressed fluorescence background of less than 0.5%. The maximum peak power and average power were estimated to be 5 W and 0.35 µW, respectively. The durability was as long as 1.7 × 104 shots/waveguide.</P>

A novel surface plasmon sensing platform has been fabricated in a flexible format. The procedure used to fabricate a grating coupler for SPR excitation combined standard replica molding techniques with room temperature nanoimprint lithography producing a smooth repeating structure 600 nm in width and 10 nm high. In initial tests the platform demonstrated an average signal-to-noise ratio in excess of 100:1 and sensitivity to changes in the bulk refractive index of water with temperature.
