We report a fully integrated microwave photonic passband filter on a silicon photonic chip. The on-chip integrated microwave photonic filter (IMPF) consists of a high-speed phase modulator (PM), a thermally tunable high-Q micro-disk resonator (MDR), and a high-speed photodetector (PD). The bandpass filtering function of the IMPF is implemented based on phase modulation and phase-modulation to intensity-modulation...
A novel optically tunable frequency-multiplying optoelectronic oscillator (OEO) to generate a high frequency microwave signal without employing an optical filter is proposed. The upper dual parallel Mach-Zehnder modulator (DP-MZM) integrated in a dual-polarization quadrature phase shift-keying (DP-QPSK) modulator is accurately biased to serve as an equivalent phase modulator (e-PM), which functions...
A new method of microwave photonic filter (MPF) with widely tunable passband is proposed and experimentally proved by using an optical-injected Fabry-Perot laser diode. It is based on the basic principle that the FP laser wavelength selectively amplified under optical injection. By applying the optical wave from a tunable-laser source (TLS) to the PM, a phase modulated optical signal is generated,...
We propose and verify a scheme to both improve the gain and linearity of the downconverted analog photonic link. We utilize the different electro-optic coefficients of the phase modulator to realize the suppression of the third-order intermodulation distortion. And the link gain is improved by full spectrum utilization. The simulation results show that the SFDR is improved by ∼14dB. And the link gain...
