This book basically gives the over view about The properties of erbiumdoped fiber amplifier (EDFA) such as gain and noise figure have been studied. By determining the characteristics of the 980nm, 1480nm 1550nm laser sources and ASE (amplified spontaneous emission) at the output of the amplifier used to determine the gain and noise figure of EDFA. This model allows to follow the signal (1550nm), pump (980nm) and ASE as they propagate along the fiber and determine population inversion .The both forward and backward propagation ASE are important in determining the overall gain and noise figure. For the amplification of more than 80 channels the DWDM (Dense Wavelength Division Multiplexing) has required CBand (15251565)nm and LBand (15651610)nm EDFA.We show that a flat gain spectrum can be achieved in the range from 1565 to 1610 nm when the EDF length, pump power and pump configuration are appropriately chosen. Special care must be taken when selecting the EDF length.

Enterococc faecalis considered to be the mostresistant bacteria of the root canal, in the presentstudy we used two types of root canal disinfectant toshow their effect on this type of bacteria, the firstis the diode laser and the second NaOCl solution withspecial concentrations and times. the study conductedon human decoronated extracted teeth, adjusted with13mm root length, filled with a suspension of E.faecalis, Samples were divided into 14 groups eachgroup consisted of 10 prepared roots, sixty sampleswere irrigated with NaOCl solution at differentconcentrations (0.5, 2.5 and 5.25) at twoselected times (2 minutes and 5 minutes) for eachconcentration.Sixty samples were irradiated at different powers (2W, 2.5W and 3W); each power at thetotal irradiation time 30 and 60 seconds. Whencomparison was made between NaOCl irrigant and diodelaser in a combination among differentconcentrations, powers and times the result showedthat 5.25 NaOCl at both 2 minutes and 5 minutes hadthe highest antimicrobial effect with no significantdifferences from 3W laser / 10 sec (6 cycles) butsignificantly different from 3W / 5 sec (6 cycles).

In this book, the design of InGaN LDs structures including multi quantum wells (MQWs) active region device are described and investigated by integrated system engineering technology computer aided design (ISE TCAD) device simulator. The parameters of the LDs structures are varied and optimized for high performance. This optimization study involves aspects such as thickness of active region, doping, thickness of stopper layer region, thickness of quantum wells and quantum barriers, number of quantum wells and several approaches to improve and achieve high efficiency, low threshold current and high output power of InGaN LDs. The basic LDs structures treated here are FabryPerot type InGaN double heterostructure (DH), separate confinement heterostructure (SCH) and multi quantum wells (MQWs).High performance LD has been obtained by using multi quantum wells incorporated with the optimized parameters. The lowest threshold current, higher external quantum efficiency and characteristic temperature are obtained when the number of InGaN well layers is two, at our laser emission wavelength of 415 nm, which is related to the problem of inhomogeneous carrier.
