Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a device for controllably steering electromagnetic radiation. The system uses a beam shaping unit to modulate the wavelength of a control beam over time and couples it with a birefringent medium. The refractive index of this medium can be adjusted by electromagnetic-induced polarization (without creating free charge carriers). As a result, it can emit a secondary electromagnetic beam whose emission angle depends on the temporal modulation of the incoming control beam, using three- or four-wave mixing processes.

Patent Abstract

Eine Strahlablenkvorrichtung (5) zum steuerbaren Ablenken elektromagnetischer Strahlung umfasst eine Strahlformeinrichtung (16) zum definierten zeitabhängigen Modulieren einer Wellenlänge (λ) eines elektromagnetischen Steuerstrahls (7) und ein mit der Strahlformeinrichtung (16) gekoppeltes doppelbrechendes Medium (14), dessen Brechzahl durch strahlungsinduzierte, dielektrische Polarisierung ohne ein Erzeugen freier Ladungsträger einstellbar ist, zum Bereitstellen eines aus dem Medium (14) ausstrahlenden elektromagnetischen Sekundärstrahls (2) durch Drei- oder Vierwellenmischung des Steuerstrahls (7) und eines elektromagnetischen Pumpstrahls (8), wobei ein Abstrahlwinkel (α, α, α) des Sekundärstrahls (2) abhängig von der zeitlichen Modulation des in das Medium (14) eingestrahlten Steuerstrahls (7) ist.
