Journal ArticleDOI
Optoelectronic oscillator for photonic systems
X.S. Yao,Lute Maleki +1 more
TL;DR: In this paper, the authors describe a novel photonic oscillator that converts continuous-light energy into stable and spectrally pure microwave signals, which can be used for high-frequency reference regeneration and distribution, high gain frequency multiplication, comb frequency and pulse generation, carrier recovery, and clock recovery.
Journal ArticleDOI
Multiloop optoelectronic oscillator
X.S. Yao,Lute Maleki +1 more
TL;DR: In this article, the authors describe and demonstrate a multiloop technique for singlemode selection in an optoelectronic oscillator (OEO) and demonstrate the first fiber-optic implementation of the carrier suppression technique to further reduce the close-to-carrier phase noise of the oscillator.
Journal ArticleDOI
High frequency optical subcarrier generator
X.S. Yao,Lute Maleki +1 more
TL;DR: In this article, an electro-optical oscillator capable of generating high stability optical signals at frequencies up to 70 GHz was described, and a comb of stable frequencies was produced by modelocking the oscillator.
Journal ArticleDOI
Coupled optoelectronic oscillators for generating both RF signal and optical pulses
X.S. Yao,L. Davis,Lute Maleki +2 more
TL;DR: In this paper, a coupled optoelectronic oscillators (COEO) constructed with a semiconductor optical amplifier-based ring laser and a colliding pulse mode-locked laser was used to generate short optical pulses and spectrally pure radio frequency (RF) signals.
Journal ArticleDOI
Dual microwave and optical oscillator.
X.S. Yao,Lute Maleki +1 more
TL;DR: In this paper, the authors describe and demonstrate a novel device in which a microwave oscillation and an optical oscillation are generated and directly coupled with each other, which is capable of simultaneously generating stable optical pulses down to the subpicosecond level and spectrally pure microwave signals at frequencies greater than 70 GHz.
