Piezoelectric optical micro-switch structure

A piezoelectric optical micro-switch structure comprising:

• a base unit;
• a first cantilevered arm base arranged on the base unit, said first cantilevered arm base is provided with a first cantilevered arm which generates a mechanical deformation;
• a second cantilevered arm base arranged on the base unit and spaced apart a predetermined distance from the first cantilevered arm base, said second cantilevered arm base is provided with a second cantilevered arm which generates a mechanical deformation;
• a first piezoelectric controller including a pair of electrodes, said first piezoelectric controller is adhered to the first cantilevered arm so as to control the mechanical deformation of the first cantilevered arm;
• a second piezoelectric controller including a pair of electrodes, said second piezoelectric controller is adhered to the second cantilevered arm so as to control the mechanical deformation of the second cantilevered arm;
• and
• an optical reflector having a mirror surface at a front side, said optical reflector is connected between the first cantilevered arm and the second first cantilevered arm to constitute an optical micro-switch;
• wherein when the first cantilevered arm and the second cantilevered arm are bent, the optical reflector can turn a predetermined bending angle and change a reflective direction of an incident light beam.
