Wavelength tuning and dynamic characteristics due to the vernier effect of a coupled-ring reflector (CRR) laser diode including active region within resonators are investigated using a split-step time-domain modelling approach. A CRR provides a strong mode-selection filter and could significantly extend the effective cavity length of a conventional Fabry-Perot laser. The simulation results for a particular design show that the tuning range as wide as 33 nm is possible with side mode suppression ratio exceeding 35dB. The modulation frequency could be 8 GHz and the frequency chirp could be in the range of 50 ~ 200 MHz/mA.
