主　　题：lithography shifted overcome 

摘      要：Multiple phase-shifted(MPS)diffraction grating is an effective way proposed to overcome the spatial hole burning(SHB)effect in a distributed feedback(DFB)*** present two symmetric λ/8 phase-shifted DFB lasers by using nanoimprint lithography(NIL).The threshold current of a typical laser is less than 15 *** side mode suppression ratio(SMSR)is still above 42 dB even at 100 mA current *** show the versatility of NIL,eight different wavelength MPS-DFB lasers on this single chip are also *** results prove that NIL is a promising tool for fabricating high performance complex grating DFB lasers.
