Abstract :
A magnetically tunable microwave spin-wave photonic oscillator was designed and modeled. A spin-wave filter made with an yttrium-iron garnet (YIG) film was used simultaneously as a frequency-selective and time-delay element. Frequency tuning of the oscillator was realized in the range of 4-8 GHz through the variation of a bias magnetic field applied to the YIG film. The phase noise was -125 dBc/Hz at 10 kHz offset and -140 dBc/Hz at 100 kHz offset from the oscillation frequency.
