摘要：

A novel photon phase state is proposed that is similar to a recently advanced state by J.H. Shapiro, S.R. Shepard and N. Wong, Phys. Rev. Lett. 62 (1989) 2377. The new state given here has a phase distribution W-phi that has a sharply-peaked central maximum with a superposed broad background. The phase noise associated with the width of the best-fitting gaussian to the central peak decreases exponentially with increasing mean photon number. The state is mathematically more tractable and perhaps physically more realizable than previous constructions.
