Abstract:
A device, comprising:an optical modulator operable to receive and modulate a signal beam to produce modulation signals in said signal beam in response to a modulation control signal; and a feedback loop having an optical portion that receives a portion of said signal beam output from said optical modulator, an optical delay module in said optical portion, and an optical-to-electrical converter converting said portion into an output signal, wherein said feedback loop produces said modulation control signal from said output signal, and wherein said optical delay module includes a first optical delay element responsive to an acceleration of the device to cause a first frequency shift in said modulation control signal and a second optical delay element optically connected to said first optical delay element and responsive to said acceleration to cause a second frequency shift in said modulation control signal that is opposite to said first frequency shift.
