Abstract
The room-temperature modulation of submillimetre wave maser radiation by free carrier absorption in germanium has been demonstrated using the `magnetic rectifier' effect. High modulation efficiencies at frequencies out to 15 × 105 Hz have been obtained. The mechanism is of use as a broad band modulation technique to wavelengths as short as 8 μm.Keywords
