Abstract
The characteristics of a spin-wave optoelectronic microwave oscillator are experimentally studied for the first time. The oscillator represents a ring structure the microwave circuit of which contains a spinwave delay line based on the yttrium–iron-garnet film. The optical part of the oscillator contains a fiberoptic delay line with a length of 100 m. It is demonstrated that the spin-wave delay line makes it possible to tune the output frequency in wide ranges at a relatively low level of the phase noise. In the gigahertz frequency range, the level of the phase noise is no greater than–110 dBc/Hz at a detuning of 10 kHz from the carrier frequency.
