  • From its inception nearly 30 years ago, the optical subdiscipline now referred to as nonimaging optics, has experienced dramatic growth. The term nonimaging optics is concerned with applications where imaging formation is not important but where effective and efficient collection , concentration, transport and distribution of light energy is - i.e. solar energy conversion, signal detection, illumination optics, measurement and testing. This book will incorporate the substantial developments of the past decade in this field.

  • The dramatic reduction in transmission loss of optical fibers coupled with very important developments in the area of light sources and detectors have resulted in phenomenal growth of the fiber optic industry during the last 35 years or so. Indeed, the birth of optical fiber communication systems coincided with the fabrication of low-loss optical fibers and the operation of room-temperature semiconductor lasers in 1970. Since then, scientific and technological growth in this field has been phenomenal.

  • A new type of semiconductor laser is studied, in which injected carriers in the active region are quantum mechanically confined in localized finite self-assembled wire-like quantumdash (Qdash) structures that are varied in sizes and compositions. Effects of such carrier distribution and quasi three-dimensional density of states contribute to a quasisupercontinuum interband lasing characteristics, which is a new laser design platform as compared to continuous broad emission spectrum generated by nonlinear media pumped with ultrashort laser pulse....

  • The ADC Outdoor Fiber Distribution Terminal 48F (oFDT-48) is designed to terminate, splice and interconnect fiber optic cables in an outdoor environment. This terminal may be adapted to Fiber-to-The-Premise (FTTP) Multiple Dwelling Unit (MDU) applications by mounting the enclosure to the exterior surface of a dwelling and connecting between the distribution cable and drops routed to individual living units. The oFDT-48 is typically divided into two side-by-side sections with distribution cable routed into one side and drop cable routed into the other side.

  • In our quest to elucidate the origin of the universe and the formation of galaxies, particularly that of the Milky Way in which we live, astounding progress has been made in recent years through observational and theoretical studies. Not only have gigantic surveys covering a large fraction of the sky brought statistics enlightening evolutionary paths of galaxies, but powerful instruments, such as radio interferometers and ground- and space-based optical/ infrared telescopes, have been able to map individual objects with high sensitivity and spatial resolution.

  • This thesis presents time-resolved measurements of the spin evolution of transient carrier populations in III-V quantum wells. Non-equilibrium distributions of spin polarisation were photoexcited and probed with picosecond laser pulses in three samples; a high mobility modulation n-doped sample containing a single GaAs/AlGaAs quantum well, an In0.11Ga0.89As/GaAs sample containing three quantum wells and, a multi-period GaAs/AlGaAs narrow quantum well sample.

  • The book opens with a section on recent advances in analytical methods. Dr. Kang Bongsu contributed a chapter that presents an alternative technique for the free and forced vibration analysis of one-dimensional distributed parameter systems. This approach is based on the idea of superimposing the amplitudes of the constituent travelling waves, rather than the traditional approach of normal mode expansion that relies on the apriori calculation of eigensolutions or assumed normal modes.
