Dual-Comb Spectrometer for Fast Wideband RF Spectral Analysis
08:30-08:45
2017-10-04 08:30 2017-10-04 08:45 America/Denver Dual-Comb Spectrometer for Fast Wideband RF Spectral Analysis We propose a novel spectrum analyzer based on heterodyne down-conversion with two detuned optical frequency combs for rapid, wideband characterization of RF signals. The measurement bandwidth of ~40 GHz is limited by modulator speed and the system latency and frequency resolution are time-bandwidth limited. Hilton Santa Fe Historic Plaza Salon I

Continuously tunable and reconfigurable microwave photonic multiband filter based on cascaded MZIs
08:45-09:00
2017-10-04 08:45 2017-10-04 09:00 America/Denver Continuously tunable and reconfigurable microwave photonic multiband filter based on cascaded MZIs A tunable and reconfigurable microwave photonic multiband filter with up to 13 simultaneous passbands is presented. All the passband frequencies are continuously tunable over 20 GHz, and the number of simultaneous passbands is highly reconfigurable between 1 to 13. Hilton Santa Fe Historic Plaza Salon I

Electro-Optic Comb Generation from Noise with a Photonically Filtered Optoelectronic Oscillator
09:00-09:15
2017-10-04 09:00 2017-10-04 09:15 America/Denver Electro-Optic Comb Generation from Noise with a Photonically Filtered Optoelectronic Oscillator We present a novel architecture for electro-optic comb generation by utilizing both optical and RF outputs of a photonically filtered optoelectronic oscillator. The output is an EO comb with 10.5 GHz combline spacing generated entirely from noise without an external driving RF signal. Hilton Santa Fe Historic Plaza Salon I

Microcomb based microwave true-time-delay beamforming
09:15-09:30
2017-10-04 09:15 2017-10-04 09:30 America/Denver Microcomb based microwave true-time-delay beamforming We propose a photonic microwave beamforming scheme based on spectral shaping of a microresonator frequency comb (microcomb) with programmable dispersive time delays. The scheme can potentially support large-scale phased arrays by exploiting the large bandwidth of microcombs. Hilton Santa Fe Historic Plaza Salon I

Application of Optical Frequency Combs in Extreme Bandwidth Signal Processing Invited
09:30-10:00
2017-10-04 09:30 2017-10-04 10:00 America/Denver Application of Optical Frequency Combs in Extreme Bandwidth Signal Processing The application of high-count multi carrier optical sources (i.e. frequency combs) in real-time microwave/millimeter wave signal processing is discussed. The multi heterodyne sensing and classification of up to 110 GHz-wide radio frequency (RF) signals using two set of optical frequency combs is demonstrated. Hilton Santa Fe Historic Plaza Salon I
