Optical switch for multimode optical-fiber systems

Optics Letters, 1979
A 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), 2003
A 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.

OPTICAL SWITCHING

2015
An optical switch (10) comprising: inputs (12) to receive input optical signals at respective wavelengths and having planar wavefronts; conversion apparatus (14) to convert each input optical signal into a respective optical signal having a respective helical wavefront, each helical wavefront having a different orbital angular momentum, OAM; optical ...

Packet switching or optical switching?

IEEE Internet Computing, 2000
One of history's main benefits is that it lets us detect trends that help predict the future. Over the past 30 years since the Internet started (1970-2000), many clear trends have emerged. The article very briefly examines the most critical of these trends, the one that led to the creation of the Internet: the packet switching cost trend.

Optical Switching Technologies and Switching in Optical Future Networks

2006 International Conference on Transparent Optical Networks, 2006
Compared with the large range of optical switching technologies that have been the subject of research, very few have been deployed on a significant scale in telecommunications networks. From an industrial and commercial viewpoint, this paper describes the current status of the more successful ones and relates them to their network applications and to ...

Integrated Optical Acousto-Optic Switching

SPIE Proceedings, 1985
Acousto-optic interactions are well known and widely used since long. The main applications for bulk optic devices are Bragg-cells for beam deflection and frequency shifting. Acousto-optic interactions using integrated otpical (I0) waveguides and surface acoustic waves (SAW) are very promising because of expected high efficiency.

Ultrafast All-Optical Switching in Optical Fibers

1990
Optical fibers have potential for generating and transmitting information at repetition rates of the order of a few THz1, that is much above the capacity of signal processors based on electronic technology. This means that a substantial improvement in the speed of a communication or computing system can be achieved if basic logic operations and signal ...
