As a result, several new acousto-optic tunable filters have been built and tested. The program is highlighted by: (1) Design, fabrication and experimental demonstration of a novel TeO2 near-collinear acousto-optic tunable filter has been designed, fabricated and tested. The device exhibits a 1.29 nm spectral resolution and a 160 mw RF drive power at 1523 nm.

Download Fiber Fabry-Perot Tunable Filter for High-speed Optical Packet Switching Book in PDF, ePub and Kindle
Tunable optical filters are important building blocks for All-Optical systems and networks. Fast optical tuning in several microseconds is necessary to perform high-speed optical packet switching. Multi- Gigabit/sec packet-switching will provide flexibility and higher network throughput when large numbers of users communicate simultaneously. One approach to achieve fast wavelength tuning is to use high-speed piezoelectrically-driven Fiber Fabry-Perot tunable filters (FFP-TFs). The requirement for tuning in microseconds raises a whole new set of challenges, such as ringing, thermostability and mechanical inertia control. It was shown that correlation between the mechanical resonance and optical response of the filter is important for the filter's speed and for mounting hardware and control circuitry optimization. These features together with the FFP-TF's high capacitance (approximately 0.25-0.5 microfarad) are being folded into building a special controller to substantially improve the shape of the driving signal and the response of the filter. The resultant controller enables tuning the high-speed FFP-TF three-orders-of- magnitude faster than that possible with standard commercial FFP-TFS. The fastest switching time achieved is 2.5 microseconds. As the result, a new packet-switched media access control protocol is being designed to minimize the searching time. The filter scans only once through the entire optical region and then tunes to all the required channels one after another in a few microseconds. It can help update Rainbow-2 Broadcast-and-Select High-Speed Wavelength Division Multiplexing All-Optical network that currently has a circuit- switched protocol using standard FFP-TFS.

This report covers Phase II work for the development of dynamically reconfigurable WDM components based on the use of collinear beam acousto-optic tunable filters (AOTF). These include optical add and drop multiplexers (ODM), optical cross-connects (OXC), and dynamic fiber amplifier equalizers (DFAE). The project included three tasks: (A) AOTF performance improvement: new designs and fabrication techniques were investigated. A demonstration model 100 GHz channel spacing AOTF was constructed that achieved 0.5 nm FWHM,

A Unique, Cutting-Edge Approach to Optical Filter Design With more and more information being transmitted over fiber-optic lines, optical filtering has become crucial to the advanced functionality of today's communications networks. Helping researchers and engineers keep pace with this rapidly evolving technology, this book presents digital processing techniques for optical filter design. This higher-level approach focuses on filter characteristics and enables readers to quickly calculate the filter response as well as tackle larger and more complex filters. The authors incorporate numerous theoretical and experimental results from the literature and discuss applications to a variety of systems-including the new wavelength division multiplexing (WDM) technology, which is fast becoming the preferred method for system upgrade and expansion. Special features of this book include: * The theory underlying various architectures that can approximate any filter function * Filter design techniques applicable to a broad range of materials systems-from silica to fiber to microelectromechanical (MEM) systems * Design examples relevant to filters for WDM systems and planar waveguide devices * 250 figures as well as problem sets for use in graduate-level studies

Download High Speed Electronically Tunable Fiber-Optic Filter Book in PDF, ePub and Kindle
During phase I, two main areas of the tunable filter were investigated intensively. The first and the most important subject was increasing the tunability of the LPG based filter device in order to enable tuning over the required wavelength range (>50nm, in C-band). The second was how to create a tunable filter device with acceptable strength and narrow bandwidth for 100 GHz DWDM applications. Tunability over a range of 50nm was successfully demonstrated during this period with the parallel configuration with electro-optic polymer composites containing nanosized ZnS crystallites. For fabricating filter device, the direct writing of the LPG through the etched optical fiber with ITO layer coated was successfully achieved. This technique eliminates the several critical uncertainties such as peak shifting coming due to chemical etching of the fibers and the peak shifting resulting from the ITO coating. Together with this approach, considerable effort was made to determine the optimal conditions of LPG writing (such as the grating period, grating length and cladding layer thickness) to yield a strong stable spectral transmission peak in the C-band.

Download Integrated Tunable Silicon-on-insulator Filters Book in PDF, ePub and Kindle
"Silicon-on-insulator (SOI) has become an attractive material system for integrated photonic components due to its potential for integration of optical devices with complementary metal-oxide-semiconductor (CMOS) technology, and its low cost. Moreover, the high-index contrast of the SOI system enables fabrication of very compact devices. Wavelength division multiplexing (WDM) is a key technique for high-capacity telecommunication and data communication networks. Optical filters are one of the key components for implementation of photonic integrated circuits (PICs), and wavelength division multiplexed (WDM) optical communication systems.Researchers have demonstrated numerous configurations such as ring resonators, Mach-Zehnder interferometers, and integrated Bragg gratings for implementation of SOI-based optical filters. The goal of this thesis is to develop novel filter configurations for application in WDM systems and photonic integrated circuits, specifically bandwidth tunable filters and optical filters with multiple channels. To achieve this goal, first we review different possible approaches to implement bandwidth tunable filters and multi-channel filters. Contra-directional grating assisted coupler(CDGAC) is chosen to implement the chosen configurations.Using CDGACs three different configurations are chosen to implement the bandwidth tunable filters. The main drawback of all of previously demonstrated SOI integrated bandwidth tunable filters is that they have a limited bandwidth tunability range. However in this thesis by cascading two CDGACs with different periods, a bandwidth tunable add-drop filter with bandwidth tuning range of 10.6 nm is implemented. This structure has a working range limited to 17 nm. In addition to that, a fully reconfigurable add-drop filter consisting of two identical CDGACs in a loop configuration is proposed. Moreover, by omitting one of the two connecting waveguides from this structure, a bandwidth-tunable bandpass filter is realized.Finally, we propose the design, fabrication and measurement results of an add-drop filter with two drop channels which is a CDGAC with two different grating periods. The performance of proposed configuration is investigated by means of Fourier analysis which gives a thorough insight into the performance of the device and can be used to understand the behavior of similar configurations.We believe that the present thesis is a step forward towards implementation of optimal bandwidth tunable SOI filters. Moreover, the proposed two-channel optical add-drop filter can have a significant impact on the required device density to perform advanced filtering functions." --
