An acousto-optic architecture is presented to implement a nonblocking space-division switch with O(N) complexity. Signal degradation is minimal so that the switch is suitable for nonregenerative application within optical networks; it is also capable of rapid reconfiguration. Experiments for a 1 x 4 switch show an insertion loss ranging from 4.6 to 5.6

Optical waveguide switch (3 × 3) for an optical switching system
Applied Optics, 1978A new optical switch element is proposed for a switching system which exchanges optical signals in optical transmission lines without optoelectric conversion. It consists of three parallel equidistant straight singlemode waveguides fabricated of an electrooptic material with electrodes deposited on them. The element, whose interaction length is pi/(2)((

It is shown theoretically that the nonlinear optical Kerr effect can be used to build an all optical configuration controlling spectral switches. The main advantage in it is that it can greatly simplify the control method compared to previous schemes using the aperture mechanism or electro-optical one.

Techniques for optical packet switching and optical burst switching
IEEE Communications Magazine, 2001Wavelength-division multiplexing appears to be the solution of choice for providing a faster networking infrastructure that can meet the explosive growth of the Internet. Several different technologies have been developed so far for the transfer of data over WDM.

Optical buffering and switching in packet switched optical networks
IEEE AFRICON. 6th Africon Conference in Africa,, 2003Optical packet switching provides the advantages of transparency and the efficient use of the bandwidth provided by WDM on optical transport networks. There are however various impediments to deploying this technology in an all-optical fashion: optical buffering is inefficient, and all-optical signal processing has not been implemented in networks.

Optical switching networks using tree‐structured waveguide optical switches
Electronics and Communications in Japan (Part I: Communications), 1987AbstractTo make a large‐sized optical matrix is an important subject in realizing optical switching systems. Although optical matrices using waveguide optical switches have potential from the viewpoint of high speed and circuit integration, they are limited in the number of input/output terminals (up to between 4 and 8) due to the insertion loss and ...

Optical switch for multimode optical-fiber systems
Optics Letters, 1979A new type of optical switch is constructed of graded-index rod lenses. It is operated mechanically by small electromagnets. This switch is compatible with practical multimode-fiber communication systems. It has many outstanding features, such as low insertion loss (1.3–1.4 dB), low crosstalk ( 2 × 106 times), and small size (40 × 50 × 25 mm3).

Optical switching technologies for fast optical packet switching
Proceedings of 2002 4th International Conference on Transparent Optical Networks (IEEE Cat. No.02EX551), 2003A survey of optical switching technologies being candidates for an optical packet switched (OPS) network is presented. Switching time range for optical switching fabrics is found through analysis. In light of this, and based on reported switch devices, switching technologies are identified as candidates for OPS.
