Embodiment Construction

[0017] figure 1 The first mentioned method for treating electromagnetic radiation is shown in . This radiation includes multiple carriers in the frequency range from 0.1 terahertz to 10 terahertz and information modulated onto each of these carriers having a signal frequency of less than 50 GHz. Among all these frequencies one has a frequency ω THz，信号 The signal of radiation 1, the receiver is to be selectively tuned to this frequency.

[0018] For this selective adjustment, the method of the present invention first employs two distributed feedback lasers (DFB lasers) 2 and 3, with which the tunable terahertz local oscillator is realized. The two DFB lasers are used to generate a laser with frequency ω 可见，1 and ω 可见，2 of two laser beams, where these frequencies are altered by changing the temperature of these lasers. In module 4, the two laser beams are subjected to a first difference frequency mixing, resulting in a frequency ω THz +M xω 1 The reference wave 5. The fr...

Abstract

The invention relates to a method for processing received electromagnetic radiation 1 having several carrier waves in the frequency range between 0.1 and 10 terahertz and information of a signal frequency of less than 50 GHz, particularly of less than 1 GHz, said information being modulated onto the carrier waves, wherein by means of a filter tunable in the frequency range between 0.1 and 10 terahertz an individual carrier wave is filtered out of the received radiation 1 as a terahertz signal, and wherein the filtered-out terahertz signal is supplied to a detection method sensitive to the signal frequency.

Description

technical field [0001] The present invention relates to a method for processing received electromagnetic radiation having a plurality of carriers in the frequency range between 0.1 teraherz and 10 teraherz and having signal frequencies modulated onto these carriers Information less than 50 GHz, especially less than 1 GHz. The invention also relates to a receiver device for implementing the method. Background technique [0002] Since the first technologies for wireless data transmission were introduced about 100 years ago, the bandwidth available for transmission has continued to grow. As is known, the frequency bandwidth available for transmission depends on the carrier frequency, so that as the frequency increases, the available transmission bandwidth also increases. Today, carrier frequencies in the range of kilohertz to multi-gigahertz are used. Therefore, the so-called "wireless HD" operates at a carrier frequency of 60GHz and a bandwidth of 4Gb / s. In order to be abl...
