Abstract
A method of managing radiation having a frequency in the terahertz and/or microwave regions. The method comprises providing a semiconducting device having a two-dimensional carrier gas. Plasma waves are generated in the carrier gas using a laser pulse. The frequency of the plasma waves, and as a result, the generated radiation are adjusted using a voltage applied to the semiconducting device.
Claims6
A method of generating terahertz radiation, the method comprising:
- selecting a bias voltage based on a desired frequency of the terahertz radiation;
- applying the bias voltage between a first contact of a semiconducting device and a plurality of contacts to a two-dimensional carrier gas of the semiconducting device;
- generating laser pulses with a laser;
- and
- shining the laser pulses directly onto the semiconducting device, wherein the shining causes the carrier gas of the semiconducting device to emit terahertz radiation having the desired frequency.
