We report that a negative refractive index (NRI) can be generated in a relativistically moving medium by breaking translational symmetry. The threshold for NRI behaviour is the medium's Čerenkov speed (εµ)–1/2.

The flatband slow light properties of a honey- comb photonic crystal waveguide in both TE and TM polarizations is discussed. With struture tuning, the waveguide may have obviously different group velocities for TE and TM modes, which makes it have the characteristics of polarizer.

By using optical fibre, a single in-building network can offer many broadband services to both wired and wireless terminals. Multi-level modulation and dispersion-robust radio-over-fibre techniques allow the use of cost-effective multimode silica or plastic fibre.

This paper elucidated how to evaluate wavefront property by precisely diagnose far field distribution. A Ф350mm far field diagnostic device was designed to be applied on the 9th beam of Shenguang-II. The performance in 2007 indicated that 70% of total energy was focused in a 5 times of the diffraction limit diameter circle, while 95% of total energy was focused in a 13 times of the diffraction limit diameter circle.
