This thesis demonstrates, in particular, the concept of an adaptive optical power splitter employing an Opto-VLSI processor and a 4-f imaging system experimentally in three stages as follow: Also, multiple input RF signals can be dynamically combined with arbitrary user-defined weights.
An adaptive OPS can also be incorporated in tunable optical dispersion compensators, optical attenuator and optical gain equalizer, and reconfigurable optical switches. By uploading optimized multicasting phase holograms onto the software-driven Opto-VLSI processor, the input RF signal is dynamically split and directed to different output ports, with userdefined splitting ratios.
An adaptive optical power splitter OPS can dynamically reallocate the opticalpower in the entire network according to the real-time distribution of users and services, thus providing numerous advantages such as improve an optical network efficiency, scalability, and reliability.
The experimental results demonstrate that the developed Opto-VLSI-based adaptive optical combiner can dynamically route multiple input optical signals to a single output, with user-defined weight profiles, thus realising a tunable microwave filter.
They also demonstrate that N input optical signals can be dynamically combined with arbitrary weights into a single optical fibre port. This will greatly enhance the efficiency of optical communication networks.
Optical splitters play an important role in passive optical network PON technology by enabling several hundred users to share one optical line terminal. Experimental results demonstrate that an input optical signal can arbitrarily be split into N signals and coupled into optical fibre ports by uploading optimized multicasting phase holograms onto the Opto-VLSI processor.
The proposed splitter structure enables an input optical power to be split adaptively into a larger number of output fibre ports, through optimized phase holograms driving the Opto-VLSI processor.
An adaptive OPS is also important for realizing self-healing ring-to-ring optical MAN, thus offering automatic communication recovery when line break occurs. The thesis also demonstrates the concept of an adaptive optical signal combiner which enables multiple signals to be combined with user-defined weight profiles into a single fibre port.
The total insertion loss of the optical power splitter is only 5 dB. Recommended Citation Mustafa, H. The new adaptive optical splitter has additional advantages including lossless operation, adequate inter-port crosstalk, compressed hardware and simple user interface.
Results also show that the optical amplifiers can compensate for the insertion and splitting losses, thus enabling lossless splitter operation.
Excellent agreement between theoretical and experimental results is demonstrated. As a proof-of-concept demonstration, two input RF signals are dynamically combined with different user-defined weight profiles.
A crosstalk level around dB and a wavelength spectral range exceeding 40 nm is experimentally realized.Study of 1x4 Optical Power Splitters with Optical Network Process, Network, Optical Splitter, Power Splitter 1.
