“…The phase noise of the generated signal in our system is not as good as that reported in [1], [6], [9]. The fundamental reason of the poorer phase noise performance is due to the short total loop length, which is about 50 meters.…”

“…is the effective open-loop gain, given by (9) When the effective open-loop gain is less than unity, (8) can be simplified to (10) The corresponding microwave power is then given by (11) Only the frequency component with a phase increment of after each loop circulation being a multiple of 2 and the total RF loss being minimum in the loop will oscillate. Therefore, when the conditions (12a) (12b) are satisfied where are integers, and the combinations of and and must meet the conditions given in (12a) and (12b), respectively, will reach a maximum and the oscillation mode with a frequency will add up in phase after each circulation.…”

“…More importantly, the frequency tunability would be complicated and the tunable range is small if a multiple-loop structure is employed. For example, a continuously frequency tunable OEO was proposed in [9], in which a wavelength-tunable laser source and two dispersive optical fiber loops were employed. The frequency tuning was realized by tuning the wavelength of the laser source.…”

Abstract-An optically tunable optoelectronic oscillator (OEO) implemented by employing a two-port optical phase modulator without using any electronic microwave filters is proposed and experimentally demonstrated. The key device in the system is the two-port phase modulator, which functions, in conjunction with a dispersive element in the loop, to form a high-Q microwave filter to perform microwave frequency selection. The central frequency of the microwave filter is a function of the optical wavelength and the chromatic dispersion of the dispersive element, therefore, the oscillation frequency can be simply tuned by tuning the wavelength of the laser source or the chromatic dispersion of the dispersive element. A theoretical analysis is provided, which is verified by experiments. The phase noise performance and the frequency tunability are both experimentally investigated.

“…Various photonic techniques which significantly improve the current state of art millimeter wave and microwave AWG have been proposed and demonstrated. The narrow band techniques which enable to generate tunable gigahertz waveforms through RF interference by employing a tunable laser diode source, electrooptic modulator, and fiber delay lines [3] and through beating of different longitudinal laser modes, which are independently phase or amplitude modulated to produce arbitrarily shaped beat signals, by utilizing mode-locked laser diode combined with a wavelength-division-demultiplexing [4] have been demonstrated. Using arrayed waveguide grating as a wavelength-division-multiplexing (WDM) scheme with a series of optical attenuators and delay lines as well permits to achieve amplitude and phase modulated gigahertz RF waveforms [2].…”

Theoretical calculations are compared with experimental generation of 120MHz square waves and 160MHz sawtooth waves and obtained good agreement.

“…Optically assisted AWGs provide much better performance than the electronic AWGs in terms of the speed, bandwidth, and the dynamic range resolution [1], [2]. Various narrow-band techniques have been proposed to generate tunable RF waveforms by creating tailored pulse sequence through direct space-to-time mapping [3] and recombining time delayed pulses through RF interference via utilizing tunable laser diode source, electrooptic modulator, and dispersive fibers [4]. Beating of different longitudinal laser modes of wavelength-division-demultiplexed mode-locked laser (MLL) pulses also enables phase or amplitude modulation to produce arbitrarily shaped beat signals [5].…”

Abstract:We demonstrate fast optical arbitrary waveform generation by using the MEMS digital micromirror arrays. The desired radio-frequency waveforms are achieved by properly shaping the spectrum of the broadband optical source via using micromirror arrays as a digital spatial light modulator preceded by wavelength-to-time mapping through the dispersive medium. We obtain up to 280-MHz sawtooth and 200-MHz square waveforms that can be controlled by using 1024 Â 768 mirror arrays in the preliminary experimental results. Based on currently available digital mirror technologies, we estimate that arbitrary waveforms up to 1-GHz rate and reconfigurable in $ 30 s are achievable by using the proposed approach.
