  Integrated circuits of photonic components are the goal of applied
polaritonics. Here, we propose a compact clock generator based on an
exciton-polariton micropillar, providing optical signal with modulation
frequency up to 100 GHz. This generator can be used for driving polariton
devices. The clock frequency can be controlled by the driving laser frequency.
The device also features low power consumption (1 pJ/pulse).
