Einleitung einer PatentanmeldungInitiation of a patent application
Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des Anspruches I.The The invention relates to a device according to the preamble of Claim I.
Anwendungsgebiet:Field of use:
Damit die wachsenden Datenraten und die Menge an Signalen bei der Intra- und Interplatinenkommunikation ohne aufwendiges HF-Elektronikdesign erzielt wird, ist eine flexible optische Signalverteilung auf dem gesamten Board erforderlich.In order to the growing data rates and the amount of signals in intra- and Interplatinenkommunikation without elaborate HF electronics design is achieved, is a flexible optical signal distribution on the entire board required.
Stand der Technik:State of the art:
Es existieren Systeme, die per Lichtwellenleiter zwischen den Leiterplatten realisiert sind und per Laserdioden einzelnen Lichtkanäle realisieren können. Ferner existieren Leiterplatten mit eingebetteten optischen Schichten, allerdings ohne effiziente, bzw. bisher lediglich aufwendig zu platzierende Ein- und Auskoppelelemente.It There are systems that use fiber optic cables between the circuit boards are realized and can realize individual light channels by laser diodes. Further there are printed circuit boards with embedded optical layers, However, without efficient, or previously only expensive to place Input and output elements.
Nachteile des Standes der Technik:Disadvantages of the prior art:
Bei den existierenden Systemen ist die Kanalmenge und die räumliche Platzierung der Lichtwellenleiter und somit die Platzierung der Sender und Empfänger auf der Platine fixiert. Somit ergeben sich Nachteile beim Leiterplattendesign. Die Ein- und Auskopplung der optischen Signale gestaltet sich aufwendig und ineffizient, da das Design vorher feststehen muss.at the existing systems is the channel set and the spatial Placement of the optical fibers and thus the placement of the Sender and receiver fixed on the board. Thus, there are disadvantages in the PCB design. The coupling and decoupling of the optical signals is elaborate and inefficient, because the design has to be fixed in advance.
Aufgabe der Erfindung:Object of the invention:
Aufgabe der Erfindung ist es, eine optische Datenübertragung auf Leiterplatten mit einer höheren Datenrate als bisher möglich zu realisieren und die räumliche Flexibilität der Sende- und Empfangselemente auf einer optischen Platine ohne Designaufwand zu erhöhen, sowie die Anzahl der möglichen Signal-Kanäle durch Kodierung der Kanaladressen zu erweitern.task The invention is an optical data transmission on printed circuit boards with a higher data rate as previously possible to realize and the spatial flexibility the transmitting and receiving elements on an optical board without Increase design effort, as well as the number of possible Signal channels by coding the channel addresses to expand.
Diese Aufgabe wird durch die Vorrichtung mit den Merkmalen des Anspruchs I gelöst.These The object is achieved by the device having the features of the claim I solved.
Lösung der Aufgabe:solution the task:
Mit dem beschriebenen Lichtbussystem werden parallele VCSEL(Laserdioden)-basierte optische Kanäle mittels den beschrieben Ein- und Auskoppelelemente planar in die optische Leiterplatte eingekoppelt und über diffraktive optische Elemente wie nachfolgend beschrieben flexibel in der optischen Zwischenschicht der Leiterplatte umgelenkt. Ferner werden die Laser-Kanäle mit unterschiedlichen Modulationsfrequenzen moduliert, um diese dann, in den Empfangsbauteilen mittels Bandpassfiltern wieder entsprechen den Zieladressen zuzuordnen.With the described light bus system are parallel VCSEL (laser diode) -based optical channels by means of the described input and output elements planar in the optical circuit board coupled and diffractive optical elements as described below flexible in the optical interface layer the circuit board deflected. Furthermore, the laser channels with different Modulation frequencies modulated to this then, in the receiving components match again using bandpass filters correspond to the destination addresses.
Vorteile der Erfindung:Advantages of the invention:
Im Gegensatz zu herkömmlichen optischen oder elektronischen Lösungen zur Platinensignalführung besteht der große Vorteil, dass mit einer optischen Zwischenschicht in der Leiterplatte gearbeitet werden kann, die nicht vorher bezüglich der Lichtführung designt werden muss, sondern flexibel mittels der beschrieben Anordnung, auf der gesamten Platinenfläche genutzt werden kann. Die optischen Kanäle werden planar in die Platine eingekoppelt und umgelenkt, so dass aufwendige Aufbauten vermieden werden können. Das gleich gilt auch für die Auskopplung auf der Empfängerseite. Mittels Kodierung durch unterschiedliche Modulationsfrequenz der parallelen Laser-Quellen ergeben sich hinsichtlich der Adressierung flexible Möglichkeiten z. B. Kreuzverteilungen etc.in the Unlike traditional optical or electronic solutions for board signal routing is the big one Advantage that with an optical intermediate layer in the circuit board can be worked, which is not previously designed with respect to the lighting must be flexible but by means of the described arrangement, on the entire board surface can be used. The optical channels become planar in the board coupled and deflected, so that complex structures are avoided can. The same applies to the decoupling on the receiver side. By coding by different modulation frequency of parallel laser sources arise in terms of addressing flexible possibilities z. B. cross distributions etc.
