Abstract:
An optical modulator, comprising:a first deflector disposed within an integrated circuit die;a diffraction grating including a metal oxide semiconductor (MOS) transistor structure in a semiconductor substrate of the integrated circuit die, the MOS transistor structure including a gate, a drain region, a source region and a channel disposed between the drain region and source region, the source and drain regions commonly coupled so as to form a capacitor, the MOS transistor structure being coupled to receive a signal, the first deflector to deflect a light beam that enters through a back side of the integrated circuit die through the MOS transistor structure, the MOS transistor structure to diffract the light beam to create a diffracted light beam, the MOS transistor structure further to modulate the deflected light beam in response to the signal.
