Title:
MULTICHANNEL OPTOELECTRONIC SWITCHING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2004/086134
Kind Code:
A1
Abstract:
The invention relates to data optical processing systems and can be used for high-performance switching systems for mass data reception and transmission. The aim of said invention is to develop a multichannel optical cluster switching system which substentially decreases loses by reducing the number of optical elements and reduces the lateral geometric size of the entire system by modifying the optical focusing system thereof. The technical aim is achieved by the fact that an additional system consisting of N formers of homocentric beams having a predefined angular width of $g(v)$m(K)a?N1/2/f is arranged between a radiator and an active element. A radiator system is disposed in a first lens focal plane, a photodetector system is arranged in a second lens focal plane, said lens being positioned in such a way that a condition $g(l) f/b>g is fulfilled, wherein a is a distance between the centres of light valve units, $g(l) is the radiator wavelength, f is the lens focus length, b is the diameter of the light valve unit and g is a distance between the centres of the photodetectors.
