We propose a novel RF photonic modulator that Is based on a coupled dual-cavity resonator. We show that such a coupled cavity system can perform efficient RF-to-optical signal conversion, in one example with more than 30 dB improvement over a single-cavity resonant modulator.
Buffer Reservoir approach is proposed and explored in order to deeply modify the dynamical behavior of solid-state lasers leading to a cancelation of resonant noise. The relaxation oscillation noise is reduced by more than 50 dB in a single frequency laser, whereas in-phase and anti-phase noise contributions are simultaneously reduced by more than 20 dB in a dual frequency laser. This approach is...
We report a photonic chip comprising multiple colliding pulse mode-locked laser and delay line-assisted Mach-Zehnder interleaver to generate 350GHz wave signal. With this mode-locked laser fourth harmonics are obtained. The interleaver quadruples the repetition rate. An integrated phase modulator enables wavelength tuning up to 0.03nm.
