Summary

Can mutual optical injection tune millimeter-wave oscillations?

Models period-one dynamics in a pair of coupled spin-VCSELs.

Proposes a tunable dual-output configuration using the lasers’ nonlinear dynamics.

Commentary

The investigated numerical regimes do not establish a fabricated transmitter’s noise or efficiency.

Shows why feedback and injection need a dynamical model in addition to a cavity solver.
