• XX7e obserxzed the directional enhancetmerat of' photoJtuttainescermce (PL) for nonresonant excitation froun catvity pol?rritons in the distribtrted I'eedbacl< (DFB) xvavegtride microcavities xvhen acavity standing NV2tV(2 utaode is resotu?tnt to 2111 excitota. The cavities consist of' a qttartz grating strb-strate xvith N70011111 pitch, a (C(5H5CgH.jNH3)zPbT.) filtaa with large exciton oscillaxtor strength,and a polystyrene filta?. They atre regarded as a nexv type of' one-ditaaensional plaotonic crystalsconsisting of resonant dispersix'e uaaateriaals which cotrple strongly to raaodes in the cr'ystals. Onthe other harnd, a dye-dispersed filnaa on the grating does not exhibit strch an enhancetaaent, whichdetnonstrsttes thatt the polariton efl'ect is essential. XVe jcoint otrt f'or periodic strtrcttrres in thestrong cotrpling regitaae that 21 un?tcroscopic jcolarization f'orutted trtader 21 reson?tnt condition naayexhibit trltrafast radi?rtive decay.
