摘要： A method of converting a modulated optical signal to an encoded electrical signal is provided. The method utilizes a device comprising an electrooptic sideband generator, an optical filter, and an optical/electrical converter. Initially, the modulated optical signal, which carries encoded optical data, is directed to an optical input of the electrooptic sideband generator. The electrooptic sideband generator is driven to generate frequency sidebands about a carrier frequency of the input optical signal. The optical filter is utilized to discriminate between the frequency sidebands and the carrier frequency and combine sidebands-of-interest to yield at least one frequency-converted optical signal comprising a millimeter wave modulation frequency. The frequency converted optical signal carries the encoded optical data and the modulation frequency is a function of the spacing of the sidebands-of-interest. The frequency-converted optical signal is directed to the optical/electrical converter where it is converted to an encoded electrical signal. Additional embodiments are disclosed and claimed.

摘要： Methods and apparatus for interference cancelation in a radio frequency communications device are described. In various embodiments a signal to be transmitted in converted into an optical signal and processed using an optical filter assembly including one or more optical filters to generate an optical interference cancelation signal. The optical interference cancelation signal is converted into an analog radio frequency interference cancelation signal using an optical to electrical converter prior to the analog radio frequency interference cancelation signal being combined with a received signal to cancel interference, e.g., self interference. The optical filter assembly can include a large number of taps, e.g., 30, 50, 100 or more. Each tap may be implemented as a separate optical filter or series of optical filters. Delays and/or gain of the optical filters can be controlled dynamically based on channel estimates which may change due to changes in the environment and/or communications device position.

In particular, the first optical waveguide arm (210) comprises an electro-optical modulator (211), that is designed to receive an incoming radio frequency signal and to modulate the single-wavelength optical signal by means of the incoming radio frequency signal, thereby producing a modulated optical signal. Moreover, the second optical waveguide arm (220) comprises: a coherent optical comb generator (221), that is designed to generate an optical wavelength comb on the basis of the single-wavelength optical signal; and a fixed optical bandpass filter (223), that is designed to filter the optical wavelength comb so as to select a portion thereof, thereby producing a filtered optical signal.

摘要： A system and methods for electro-optical modulation are presented. A first optical signal and a second optical signal are optically coupled to produce a local oscillator signal propagated in two signal paths. The local oscillator signal in the first signal path and the second signal path is electro-optically phase modulated with a radio frequency electrical signal to produce a first phase modulated optical signal and a second phase modulated optical signal respectively. The first phase modulated optical signal and the second phase modulated optical signal are optically coupled to produce an intensity modulated signal comprising an RF frequency of the radio frequency electrical signal frequency mixed by a local oscillator frequency of the local oscillator signal.
