Optical modulation of ZnO microwire optical resonators with a parallelogram cross-section

A novel ZnO microwire optical resonator with a parallelogram cross-section is fabricated, which can effectively control the light field in two dimensions. Wave-guided Fabry-Perot modes with different polarizations are directly observed and further investigated systematically. Such a ZnO optical resonator offers another building block for the development of optoelectronic devices.
