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

Axial nonuniformities in the carrier density profile of 1.55 mu m capped-mesa-buried-heterostructure distributed-feedback (CMBH-DFB) InGaAsP-InP diode lasers are discussed. This is accomplished by directly measuring the spontaneous emission at variou

Summary form only given. We report the use ofa dual transverse mode diode laser for the generation of THz modulated light. Simultaneous operation on both transverse modes and subsequent mode-locking of the longitudinal wavevectors of these modes lead

The observation of electron leakage from the active layer to the p-binary layer in 1.3 /spl mu/m InGaAsP/InP Covered Mesa Buried Heterostructure lasers is linked to the problem of acceptor deficiency at the p-P junction via measurements of the "exces

Static and dynamic characteristics of 1.55- mu m distributed-feedback (DFB) lasers with longitudinal nonuniformity in optical intensity and carrier density are discussed. The nonuniformity is manifested in soft light-current threshold and varying dif

We have attempted to reproduce measurements which claim to demonstrate that vitreous silica at 4 K sorbs 4He, and that the sorbed 4He greatly increases the specific heat at temperatures below 3 K. We conclude that such an effect is not intrinsic to v

The influence of laser phase noise on a 400-Mb/s optical DPSK (differential phase-shift keying) system is experimentally investigated with linewidths ranging from 1.2 MHz to 8 MHz. This range corresponds to linewidth to bit rate ratios epsilon of 0.3
