Analysis of VFSO System Integrated With BPLC
ISBN: 9783659250545 / Angielski / Miękka / 2014 / 68 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The new integrated system of visible free space optic and broadband powerline communication which uses already installed powerline cables and white LEDs as a communication channel is presented. The currently exist problems in integrated system degrades the whole system performance significantly. Therefore, in this work, an optimum OFDM modulating signal power, proper DC biasing point and LED dynamic range are presented for the integrated system. Besides using OFDM modulation a practical LED model is also presented and the performance of integrated system in terms of OFDM signal power versus...

Soliton Coding for Secured Optical Communication Link
ISBN: 9789812871602 / Angielski / Miękka / 2014 / 58 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Nonlinear behavior of light such as chaos can be observed during propagation of a laser beam inside the microring resonator (MRR) systems. This Brief highlights the design of a system of MRRs to generate a series of logic codes. An optical soliton is used to generate an entangled photon. The ultra-short soliton pulses provide the required communication signals to generate a pair of polarization entangled photons required for quantum keys. In the frequency domain, MRRs can be used to generate optical millimetre-wave solitons with a broadband frequency of 0-100 GHz. The soliton signals are...

Microring Resonator for Secured Optical Communication
ISBN: 9781500587697 / Angielski / Miękka / 2014 / 70 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. A novel system of dark soliton array (DSA) for secured communication generated by using the multiplexed dark soliton pulses is proposed. The multi soliton pulses with relevant parameters are input into the micro ring resonators system with the radii of 10 m and 5 m, where the dynamic dark solitons can be controlled and generated. The DSA are obtained by using a series micro ring resonators with parameters where in the wavelength range of 1.56, 1.58 and1.60. For security applications, the DSA can be tuned and amplified. Thus, the use of DSA for high capacity which can be realized by using...

Soliton and Radio Over Fiber (Rof) Applications
ISBN: 9783848417230 / Angielski / Miękka / 2014 / 84 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. A system of microring resonators (MRRs) connected to an optical modified add/drop filter system is used. The optical soliton pulse of 60 GHz frequency band can be generated and used for millimeter waves in radio over fiber (ROF) applications. Wireless Personal Area Network (WPAN) as IEEE 802.15.3c is one of the applications for the ROF. The system uses chaotic signals generated by a Gaussian laser pulse propagating within a nonlinear MRRs system. The chaotic signals can be generated via a series of MRRs. The IEEE 802.15.3c standard operates at the 60 GHz frequency band, and it is applicable...
