OPTICAL DEVICE FOR GENERATING AND MODULATING THZ AND OTHER HIGH FREQUENCY SIGNALS

摘要

Optical generation and modulation is carried out in the optical domain and converted to, for example, the THz band using suitable optical/electrical conversion hardware. In accordance with one embodiment of the present invention, an electrooptic modulator is significantly overdriven to create sidebands on an optical carrier signal. An arrayed waveguide grating or other suitable filter is then used to filter the optical signal and remove the carrier signal and unwanted sidebands. The desired sidebands are then combined to create an optical signal that can be encoded with data through suitable modulation. Additional embodiments are disclosed.
