Heterodyne mixing of millimetre electromagnetic waves and sub-THz sound in a semiconductor device
(2016)
Journal Article
We demonstrate heterodyne mixing of a 94 GHz millimetre wave photonic signal, supplied by a Gunn diode oscillator, with coherent acoustic waves of frequency ~ 100 GHz, generated by pulsed laser excitation of a semiconductor surface. The mixing takes... Read More about Heterodyne mixing of millimetre electromagnetic waves and sub-THz sound in a semiconductor device.
