Dispersion requirements in coherent frequency-to-time mapping
Torres Company, Víctor; Leaird, Daniel E.; Weiner, Andrew M. Optical Society of America (2011)The frequency-to-time mapping technique (also known as the temporal far-field phenomenon) usually requires a significant amount of dispersion to stretch an ultrashort optical pulse so that the intensity profile becomes ... -
Multichannel Radio-Frequency Arbitrary Waveform Generation Based on Multiwavelength Comb Switching and 2-D Line-by-Line Pulse Shaping
Torres Company, Víctor; Metcalf, Andrew J.; Leaird, Daniel E.; Weiner, Andrew M. IEEE (2012-06)We demonstrate a multichannel time-multiplexed radio-frequency arbitrary waveform generator. The system combines a switching scheme of multiwavelength optical frequency combs with a novel 2-D line-by-line pulse shaper ... -
Multitap microwave photonic filters with programmable phase response via optical frequency comb shaping
Song, Minhyup; Torres Company, Víctor; Metcalf, Andrew J.; Weiner, Andrew M. Optical Society of America (2012)We present a programmable multitap microwave photonic filter with an arbitrary phase response operating over a broad bandwidth. Complex coefficient taps are achieved by optical line-by-line pulse shaping on a 10 GHz flat ... -
Noise Comparison of RF Photonic Filters Based on Coherent and Incoherent Multiwavelength Sources
Song, Minhyup; Torres Company, Víctor; Weiner, Andrew M. IEEE (2012)A filtered microwave photonic (MWP) link implemented with an optical frequency comb as a multitap optical source offers a significant improvement in noise characteristics when compared to a spectrally sliced broadband incoherent ... -
Simultaneous broadband microwave downconversion and programmable complex filtering by optical frequency comb shaping
Torres Company, Víctor; Leaird, Daniel E.; Weiner, Andrew M. Optical Society of America (2012)High-repetition-rate optical frequency combs can act as broadband photonic mixers and downconvert a microwave signal to an intermediate frequency (IF) band so that it becomes accessible with high-speed electronics. In this ...
