One of the most interesting and complex types of group behaviors in animals is that in which several organisms simultaneously repeat the same activity at regular intervals of time.1 In ordinary usage, this kind of behavior is called “synchronous”. It has been observed in Thailand that male Pteroptyx malaccae fireflies, congregated in trees, flash in rhythmic synchrony with a period of about 560 ± 6 msec (at 28°C). Males of a China’s special species of firefly called Qiongyuying flash synchronously during mating season. And we also observed that bees crawling in the same small area display a synchrony of wings fluttering. Moreover, synchrony has been described in a range of mammal groups, including odontocete cetaceans (a kind of toothed whale).2 The odontocete cetaceans behave synchronously when they breathe on the surface of water.

In the microcosm, a synthetic gene oscillator whose oscillatory cycle can be tuned by altering inducer levels, temperature and the media source has been designed by I and his cooperators to accomplish the synchronous oscillation. It uses both E.coli and yeast as component cells. In this oscillator system, chemicals (IPTG, arabinose) are used as a series of signals to initiate synchronous oscillations within single cells of the colony.3

Compared with chemical molecules, optical signal is more efficient for both the macrocosm and the microcosm. We wonder whether we can change the induced signal into light, which is visible and easy to control. It propagates much faster and has countless channels, for each wavelength is a different channel.
