We propose and demonstrate experimentally a novel technique for packet switching on a ring network. We use the wavelength dimension to increase the transmission line rate and a novel packet-stacking technique to add/drop packets. Packet stacking is u

A study is made of the factors that influence the suppression of the second TE Bragg mode in conventional 1.55 mu m capped-mesa-buried-heterostructure distributed-feedback (CMBH-DFB) lasers. It is shown that the TE side-mode suppression becomes incre
