“…The new architecture consists of nanocells based on cognitive radio technology using all-optical multicast using semiconductor ring laser (SRL). Due to strong cavity enhanced four-wave mixing (CE -FWM) in the SRL [9], several modes are periodically enhanced in power and mirrored around the main mode. Each enhanced mode has same data and is utilized for nanocell unique wavelength.…”

Abstract. The use of smart phone and tablet applications will provide the troops for executing, controlling and analyzing sophisticated operations with the commanders providing crucial documents directly to troops wherever and whenever needed. Wireless mesh networks (WMNs) is a cutting edge networking technology which is capable of supporting Joint Tactical radio System (JTRS).WMNs are capable of providing the much needed bandwidth for applications like hand held radios and communication for airborne and ground vehicles. Routing management tasks can be efficiently handled through WMNs through a central command control center. As the spectrum space is congested, cognitive radios are a much welcome technology that will provide much needed bandwidth. They can self-configure themselves, can adapt themselves to the user requirement, provide dynamic spectrum access for minimizing interference and also deliver optimal power output. Sometimes in the indoor environment, there are poor signal issues and reduced coverage. In this paper, a solution utilizing (CR WMNs) over optical network is presented by creating nanocells (PCs) inside the indoor environment. The phenomenon of four-wave mixing (FWM) is exploited to generate all-optical multicast using semiconductor ring laser (SRL). As a result same signal is transmitted at different wavelengths. Every PC is assigned a unique wavelength. By using CR technology in conjunction with PC will not only solve network coverage issue but will provide a good bandwidth to the secondary users.

“…Due to CE-FWM, the cavity modes (m −3 , m −6 , m 3 and m 6 ) are locked in phase and are periodically enhanced in the amplitude. According to the standard mode-locking (ML) theory, the beating between the cavity modes results in a periodical modulation of the optical signal with a frequency equal to the frequency spacing between the modes, as demonstrated in [1], and produces a tremendous RF tone purity. As g. 2 illustrates, the generated RF frequency is 3× of the SRL free spectrum range (FSR).…”

“…These enhanced FWM modes are mirrored around the main lasing mode of SRL at xed period in the wavelength. This type of FWM is named as cavity enhanced FWM (CE-FWM) and is rst reported in SRLs by Furst and Sorel [1]. We have previously reported the conversion of 4 Gbits/sec data onto a 60 GHz tunable mm-wave optical carrier.…”

Millimeter wave (mm-wave) technology is signicant for military needs and applications due to its numerous advantages, such as huge bandwidth, deploying small antenna and high radar resolution. Due to atmospheric inuence, mm-wave is important in short-range applications such as re control radar. Similarly for the nextgeneration communication and military applications, high-speed radio over ber networks are very crucial. In this paper, a review of the generation and modulation of millimeter-wave signal optically using semiconductor ring laser (SRL) has been done. The phenomena of optical injection locking and four-wave mixing are exploited in SRL to generate radio frequency (RF) optical signals. The signals with huge data rate can be transferred directly from an intensity modulated optical signal onto a RF optical signal with RF frequency tunable in steps of the free spectrum range (FSR) of SRL. They can be converted with exible RF modulation formats over the optical carrier.

“…Directional bistability is a key characteristic of SRL [9] and a variety of applications are based on it including all-optical logic [9], label swapping [10], all-optical memory [11], and optical regeneration [12]. The phenomena of OIL and four-wave mixing [13] have been reported in the SRL at particular conditions. A variety of applications has been reported using these two phenomena such as bandwidth enhancement [5,6], all-optical multicast [14], all-optical logic gates [15] and millimetre wave (mm wave) generation and modulation [16].…”

It has been successfully investigated for the rst time that strength of optical injection locking also depends on the size of semiconductor ring laser. Theoretical study for frequency response of optical injection locking semiconductor ring laser in the master slave conguration using direct, amplitude and phase modulation of master laser is discussed. In the unidirectional regime the locking range of semiconductor ring laser becomes wider when semiconductor ring laser with smaller size is used. Simulation results predict an incredible enhancement in the modulation bandwidth (> 500 GHz) of the slave semiconductor ring laser when used with smaller laser cavity length (50 µm) in the stable unidirectional regime.
