“…based on six different mechanisms or devices: direct modulation [5], [6], external modulation [7], [8], optoelectronic oscillators (OEOs) [9], [10], optical heterodyne [11]- [13], dualmode lasers [14]- [17], and period-one (P1) nonlinear dynamics in semiconductor lasers [18]- [30]. For the schemes based on direct and external modulation, their generated microwave signals usually have a limited frequency by the relaxation oscillation of the used semiconductor laser or the modulator bandwidth [5].…”

A photonic microwave harmonic up-conversion is experimentally demonstrated using the local oscillator (LO) to directly modulate the distributed feedback laser and externally modulate the polarization modulator simultaneously. By feeding the initial radio frequency signal generated by the LO into the system, the second and fourth harmonic photonic microwaves are eventually available through the separation of the polarization beam splitter. The steady second and fourth harmonic photonic microwaves have a linewidth of about 100 Hz and a discrepancy of up to 60 dB between the central peak and the noise floor. Undesired harmonics and sidebands in the 30 GHz, 60 GHz, and 80 GHz fourth harmonic photonic microwaves can be suppressed without the use of optical amplifiers, resulting in a clear display of both tones. The single-sideband (SSB) phase noise of this proposed system adds about 6 dB of SSB phase noise in each cumulative harmonic, which is close to the ideal state.

“…Microwave photonics is a discipline that researches the interaction between microwave and optical signals [1,2]. In the past few years, microwave photonic filters (MPFs) have attracted considerable attention owing to their inherent characteristics, such as high bandwidth, low loss, light weight, wideband tunability, reconfigurability and good resistance to electromagnetic interference [3][4][5][6].…”

A novel approach to realize a microwave photonic filter (MPF) based on gain-switched optical pulses is proposed and demonstrated. The proposed MPF using directly modulation-based optical source is more flexible and simple than using an external modulation-based optical frequency comb source. A theoretical model describing the principle of the proposed MPF is derived, which is confirmed by experimental results. Under different modulation and injection parameters, we present a numerical simulation of the frequency response of the proposed MPF. With no discernible tones, the proposed MPF is demonstrated by a proof-of-concept experiment. A single passband is achieved, which can be continuously tuned from 1 to 30 GHz. Further, self-phase modulation is explored in the optical domain to broaden the spectrum of gain-switched optical pulses and narrow down the bandwidth of the MPF passband.
