Optical Code Division Multiplexing (OCDMA) is a method used to enable simultaneous transmission of multiple optical data flows over the same fiber using the same wavelength. In OCDMA, isolation between different data flows is achieved using a set of uncorrelated, or loosely correlated, spreading codes to encode the transmitted signal and decode it at the receiver side. The process of encoding and decoding is performed entirely in the optical domain. This increases the granularity of traffic isolation in the optical domain while maintaining higher speed switching because of the alloptical encoding/decoding capability. Although code division multiplexing is a well established technique in wireless transmission where all processing of data and switching are performed electronically, there are many challenges in applying this scheme in the optical domain mainly due to the different characteristics of the medium and the signals values. This book addresses three main aspects of OCDMA: Use of OCDMA for sub wavelength switching, modeling the performance of OCDMA switching, and design of new mechanisms to enhance the performance of OCDMA.

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.

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.

The optical signals pass through a number of components such as optical fibers, filters, multiplexers and switches. These components increase the amount of total dispersion. Dispersion or pulse spreading of the optical signals is a problem which limits the bandwidth and length of the information carrying fiber. Therefore, it is important to control and characterize the dispersion. In this work, our target is to find and characterize the wavelength dependence dispersion and to see the effect of fiber Bragg grating (FBG) as a dispersion compensator. A 100 km single mode (SM) fiber optic link has been chosen. Laser diode has been chosen for light source. The channel achieve a BER = 10 11 after propagating through the 100 km singlemode fiber.

The Paris 3 is a longrange compact laser flare used for directional signaling at ranges up to 20 miles. Unlike traditional lasers the Paris 3 fan laser utilizes laser light line technology to reshape the laser from a light spot to a light line. At a range of five miles the Paris 3 fan laser will project a line of light approximately 1 400 feet in length. This makes the Paris 3 significantly more effective as a SAR signaling device than traditional beam lasers. At close ranges the Paris 3 laser can also be superbly effective as a signaling/warning device. On the battlefield beam lasers have been deployed at check points to warn off approaching vehicles. At 1000 feet focusing a spot laser on a moving automobile windshield can be challenging. Conversely the Paris 3 fan laser will project a fifty+ foot line at this range dramatically increasing the probability that the signal will be recognized. The Paris family of beacons has been engineered to be the most durable available. Constructed from a solid billet of aircraft aluminum the Paris cylinder walls are more than 2.5mm thick making the beacon virtually crush proof. This tremendous strength coupled with a water tight design and corrosion resistant coatings make the Paris laser superbly suited for all operations. The Paris 3 is turned ON and OFF by rotating the antiroll bezel. Powered by two CR123A lithium batteries the Paris 3 will provide 12 hours of operation at a constant brightness. The Paris 3 includes a 550 cord retention lanyard (not pictured) and can be weapon mounted using conventional light/laser mounts. Size (IR Red): 4.4 x 1 111mm x 25 mm. Switching: Rotate bezel. Light Generation: SolidState Laser Diode Constant Brightness. WaveLength: 880nm IR (902832). Beam Coverage: 3 Degree fan. Laser Safety: Classification US Laser Class 3C.
