10 GHz Generation with Ultra-Low Phase Noise via the Transfer Oscillator Technique
Nicholas V. Nardelli, Tara M. Fortier, Marco Pomponio +4
Coherent frequency division of high-stability optical sources permits the extraction of microwave signals with ultra-low phase noise, enabling their application to systems with str…
An integrated low phase noise radiation-pressure-driven optomechanical oscillator chipset
X. Luan, Y. Huang, Y. Li +13
High-quality frequency references are the cornerstones in position, navigation and timing applications of both scientific and commercial domains. Optomechanical oscillators, with d…
Operation of an optically coherent frequency comb outside the metrology lab
Laura C. Sinclair, Ian Coddington, William C. Swann +4
We demonstrate a self-referenced fiber frequency comb that can operate outside the well-controlled optical laboratory. The frequency comb has residual optical linewidths of < 1 Hz,…
Feedback and harmonic locking of slot-type optomechanical oscillators to external low-noise reference clocks
Jiangjun Zheng, Ying Li, Noam Goldberg +8
We demonstrate feedback and harmonic locking of chip-scale slot-type optomechanical oscillators to external low-noise reference clocks, with suppressed timing jitter by three order…
Analysis of shot noise in the detection of ultrashort optical pulse trains
Franklyn Quinlan, Tara M. Fortier, Haifeng Jiang +1
We present a frequency domain model of shot noise in the photodetection of ultrashort optical pulse trains using a time-varying analysis. Shot noise-limited photocurrent power spec…
Photonic microwave generation with high-power photodiodes
Tara M. Fortier, Franklyn Quinlan, Archita Hati +5
We utilize and characterize high-power, high-linearity modified uni-traveling carrier (MUTC) photodiodes for low-phase-noise photonic microwave generation based on optical frequenc…
Sub-femtosecond absolute timing precision with a 10 GHz hybrid photonic-microwave oscillator
T. M. Fortier, C. W. Nelson, A. Hati +10
We present an optical-electronic approach to generating microwave signals with high spectral purity. By circumventing shot noise and operating near fundamental thermal limits, we d…
