All-optical wavelength conversion and clock division utilizing semiconductor laser
TL;DRAbstract
We numerically and experimentally demonstrate a technique for performing all optical wavelength conversion with simultaneous clock division based on the period-one oscillation and cross-gain modulation effect in an optically injected semiconductor laser. Through the numerically simulation, the results that 18 GHz divided optical clock with wavelength down conversion of 5 nm can be obtained from 2 × 18 Gb/s optical time division multiplexed data stream. Moreover, the dependence of output signal on signal light strength, probe light strength, wavelength detuning, and bias current are also investigated, respectively. A proof-concept experiment is demonstrated with 12.4 GHz optical clock division and 4.33 nm wavelength down conversion. The experimental results are consistent well with that of the numerical simulations.
