Coherent emission of two optical tones with a radiofrequency (RF) tunable beatnote can spur many microwave photonics applications. Indeed, it can be useful for radars, remote sensing, or in the metrological context of ultra-stable RF frequency standards. A birefringent crystal can be inserted inside the external cavity of a VECSEL (vertical-external-cavity surface-emitting lasers) to produce a tunable very low-noise RF beatnote out of two orthogonal linear polarizations. Such dual-frequency semiconductor lasers operating along the D₂ line of cesium have been developed for CPT (coherent population trapping) atomic clocks. The development of these clocks corresponds to a need to find a trade-off between size and performance. First, intensity ...
