This article addresses a synchronization phenomenon between two uncoupled oscillators subject to a
common random external signal. Phase reduction is the most powerful technique for analytically
studying the synchronization phenomena of oscillators. After briefly introducing the phase reduction
theory, we review the theoretical results of the phase reduction analysis for the synchronization induced
by a common random signal and show that it is a universal phenomenon that can occur in a variety of
oscillators. Then we review recent experimental observation of common-random-signal induced
synchronization in semiconductor lasers.
