Abstract
We describe optical bistability in monolithically integrated, curved-mirror Fabry–Perot microcavities. The cavities were fabricated by controlled formation of circular delamination buckles within sputtered multilayers. The dominant source of the bistability is heating due to residual absorption in the mirror layers, which leads to out-of-plane deflection of the buckled mirror. Hysteresis occurs for submilliwatt input powers.
