| Summary: | Generation of dual-wavelength using passive semiconductor microring resonator with two sections of apodized
grating with total length of 26 �m on the right and left sides is presented here. In this research we use the timedomain
travelling wave (TDTW) method to model and simulate the microring resonator made of InGaAsP/InP
waveguide. Microring resonator based optical mirrors and band-limited reflectors have been the subject of
intense investigations in recent years. Therefore, we propose the microring resonator made of InGaAsP/InP
waveguide having two sides grating section. The grating sections have a trapezoidal profile. The gratings provide
the means to suppress repetition of the reflection spectrum at every free spectral range (FSR) removed from
the design wavelength. The total grating length is 26 �m (each grating side has length of 13 �m), where the
total circumference of the microring resonator is 526 �m. Propagation of the input Gaussian pulse (with 10 mW
power and bandwidth of 0.76 ps) within the grating sections is presented, where it shows a good confinement
of the propagation within the waveguide. As a result, multiple dual-wavelengths with tunable spacing within a
range of 127 pm (15.8 GHz) and 237 pm (29.6 GHz) could be generated at the throughput port of the microring
resonator. The dispersion of the grating section versus the total grating length and the frequency response
of the throughput port output signals are presented. The generated dual-wavelength has many applications
in optical sensing, radio frequency (RF) radiation, optical communication, optical switching, millimetre wave
generators and biological research. |
