Abstract: Abstract A dispersion-compensated polarization Sagnac interferometer (DCPSI) can obtain interference fringes, and then be applied to many fields. Using two identical blazed gratings in DCPSI, and the grating period of blazed gratings should be considerably… read more here.

Abstract: Abstract We theoretically and experimentally demonstrated the existence of dual loss peaks in the transmission spectrum of long-period fiber gratings (LPFGs) fabricated in a parameter-optimized two-mode fiber for the mode coupling between LP01 and LP11… read more here.
