Low-noise and accessible millimeter-wave sources are critical for emergent
telecommunications, applications de radar et de détection. Current limitations to
realizing low-noise, les systèmes à ondes millimétriques déployables incluent la taille, poids,
et le pouvoir (Échanger) exigences, avec des principes de fonctionnement complexes. In this
paper we provide a compact photonic implementation for generating low phase
noise millimeter-waves, which significantly simplifies the architecture and
reduces the volume compared to alternative approaches. Two commercial diode
lasers are self-injection-locked to a micro-Fabry-Perot cavity, and their
heterodyne provides low phase noise millimeter waves reaching -148 dBc/Hz at 1
MHz offset on a 111.45 GHz carrier. Phase noise characterization at such levels
and frequencies poses unique challenges, and we further highlight the
capabilities of optically-based measurement techniques. Our approach to
millimeter-wave generation can leverage advances in photonic integration for
further miniaturization and packaging, thus providing a unique source of
accessible, compact, and low-noise millimeter waves.
