We propose a Y splitter in a two-dimensional photonic crystal with a triangular lattice of air holes suitable for mechanooptical switching. Full switching between the two output ports can be achieved at a certain wavelength owing to the presence of a resonant central cavity with well-chosen symmetry. Experimental results confirm the operation of the device and its potential as an ultracompact mechanical switch.
