We propose a new system of the secret data encoding using a quantum memory that can be formed the high capacity secret codes for camera security. The high capacity encoding is formed by using the spatial mode of the soliton pulse, where the selected output can be stored and the quantum code generated. The perfect security concept by using the single photon property can be used within the embedded device in the camera.

Proposal of the nano-sensing device and system using a nano-waveguide transducer for distributed sensors

We propose a new concept of a distributed sensing system using a nano-waveguide and an array waveguide. The small change in physical quantity affects the change in device parameters such as refractive index or length, which is relatively absorbed and observed by the resonant wavelength. In principle, the dense wavelength separation is generated by using a soliton pulse propagating within a ring resonator system, whereas a resonant signal can be stored within the nano-waveguide, i.e. a transducer, which is formed by the sensing device. Induced change in the resonant signal at each wavelength occurs, and can be detected by using the optical spectrum analyzer. Such a proposed device is suitable to perform the measurements in the nano-scale regime such as force, stress and temperature. Moreover, the distributed or multiplexed sensing applications are also available using the nano-waveguide sensing device incorporating the array waveguide, which is discussed in details. Quantum measurement using the same system is also described. © 2009 Elsevier GmbH. All rights reserved.

Proposed solar energy conversion and storage system using a nano-ring in an array waveguide

We propose the new solar energy conversion and storage system using the array waveguide. It can be used to generate and store solar energy within the nano-array waveguide system. The system consists of micro- and nano-ring resonators incorporating a Mach Zhender Interferometer (MZI) that can be integrated into a single system. The large bandwidth signal, i.e. white light, is generated using a soliton pulse in a Kerr-type nonlinear medium propagating within a micro-ring resonator system. The control light concept is applied using a nano-waveguide incorporating an MZI, whereas the incoherent light is filtered being coherence, which is amplified and stored within the system. The white light can be re-generated using the stored coherent light pulse. Furthermore, the combination of signals is formed by the array waveguide, which is allowed to generate the huge amount of solar energy output. © 2009 Elsevier GmbH All rights reserved.

We propose a new system of the darkbright solitons conversion using a micro- and nano-ring resonators incorporating an optical add/drop filter, where the add/drop filter can be used to convert the dark soliton to bright soliton. The key advantage of the system is that the detection of the dark soliton pulse is normally difficult due to low level of input power. Firstly, a dark soliton pulse is input into a micro-ring resonator, then propagating into smaller micro- and nano-ring resonators. Secondly, the add/drop filter is applied (connected) into the ring system, where the bright and the dark solitons are obtained via the drop and through (or throughput) the ports of the add/drop filter, respectively. The results obtained have shown that the detected soliton power can be controlled by the input soliton power and the ring resonator coupling coefficient, which is enough to use in the transmission link. The optical and the quantum networks using dark soliton are also discussed. © 2009 Elsevier GmbH. All rights reserved.

We propose a novel system of a nano-waveguide that can be used to generate the continuous optical spectrum, i.e. white light. A system consists of two micro-ring resonators and a nano-ring resonator that can be integrated into a single system. The large bandwidth signal is generated using a soliton pulse propagating within a Kerr-type nonlinear medium, whereas the continuous bandwidth or wavelength of light signal can be performed. Results obtained have shown the potential of using such a system for white light source generation and amplification, which is discussed. The amplified pulse can be stored within a nano-waveguide, which is allowed to form the continuous spectrum after amplification. Alternatively, the low-level solar radiation can be amplified, and the bandwidth signals can also be enlarged. © 2009 Elsevier GmbH.

We propose a novel system of a nano-waveguide that can be used to generate the continuous spectrum, i.e. white light. The simultaneous trapping and generation of short and millimeter waves can also be performed by using either bright or dark soliton. A system consists of two micro- and a nano-ring resonators that can be integrated into a single system. The large bandwidth is generated by a soliton pulse within a Kerr-type nonlinear medium where the continuous bandwidth or wavelength can be performed. The simultaneous dark-bright solitons conversion is performed and achieved. Results obtained have shown the potential of using the technique for continuing light spectra generation, where the filtering signals are allowed by using the suitable device parameters. The advantage is that the large bandwidth separation of the short and sub-millimeter waves can be obtained, which is allowed to form the simultaneous generation of short and millimeter waves within a single system. Further, light pulse can be trapped within a nano-waveguide, which is available to form the memory device. © 2009 Elsevier GmbH. All rights reserved.

We propose a new design of a security camera system that uses the dense wavelength division multiplexing wavelength enhancement, whereas increasing in channel capacity and security can be provided. The increasing in number of channel can be obtained by the increasing in wavelength density, while the security is introduced by the specific wavelength filter, which is operated by the central operator. The optical communication wavelength enhancement is reviewed. The advantage is that the proposed system can be implemented and used incorporating with the existed communication link in either wire/wireless system, where the human privacy can be provided, which is discussed in details.

We propose a novel system of a nano-waveguide that can be used to generate the continuous spectrum, that is, white light. The simultaneous generation of short and sub-millimeter waves can also be generated by using either dark or bright soliton schemes. A system consists of two microring and a nanoring resonators that can be integrated into a single system. The large bandwidth is generated by a soliton pulse within a Kerr type nonlinear medium where the continuous bandwidth or wavelength can be performed. Results of the bright soliton obtained have shown the potential of using the technique for white light source generation and detection, which is discussed. The simultaneous generation of short and millimeter waves using dark soliton is also proposed. The advantage is that the large bandwidth separation of the short and sub-millimeter waves can be obtained, which is allowed the simultaneous generation of short and millimeter waves. © 2009 Wiley Periodicals, Inc.

We propose a new concept of a nano-sensing transducer system using a nano-waveguide. The small change in physical quantity affects to the change in device parameters such as refractive index or length which is relatively absorbed and observed by the resonant signal. In principle, the stored light pulse at the specified wavelength is generated by using a soliton propagating within the input ring resonators, whereas a resonant signal can be stored within the nano-waveguide, i.e. a transducer, which is formed the sensing ring device. The induced change in the resonant signal is occurred, and can be detected by using the wavelength domain detector (optical spectrum analyzer). Such a proposed device is suitable to perform the measurements in the nano-scale regime such as force, stress and temperature. © 2009 Elsevier B.V. All rights reserved.
