This paper reports the experimental observation and theoretical investigation of discrete time crystals (DTCs) in a Kerr-nonlinear optical microcavity. The system uses self-injection locking of two lasers to two cavity modes and a dissipative Kerr soliton to realize DTCs, including defect-carrying DTCs and phase transitions. The room-temperature, chip-scale nature of this system makes it suitable for real-world applications.
