Broadband Optical Modulator

Broadband Optical Modulator for intensity modulation.


The modulator is a reflective diffraction grating with controllable groove depth. It is capable of far field intensity modulation of a reflected laser beam by varying between an unpowered flat mirror-state and a powered diffractive state either gradually or in a binary fashion. The device design is based on BMC’s heritage deformable mirror technology that uses hysteresis-free electrostatic actuators to deform a continuous mirror facesheet. The device microfabrication process has the purpose of producing optical modulators in a cost-effective manner using commercial semiconductor batch processing techniques.
