| 1 | Multiwavelength generation using an add-drop microring resonator integrated with an InGaAsP/InP sampled grating distributed feedback显示文摘A system of an add-drop microring resonator integrated with a sampled grating distributed feedback(SG-DFB) is investigated via modeling and simulation with the time-domain traveling wave(TDTW)method.The proposed microring resonator comprises a SiO_2 waveguide integrated with an In Ga As P/In P SG-DFB,and the SiO_2 waveguide consists of a silicon core having a refractive index of 3.48 and Kerr coefficient of 4.5 × 10^(-18)m^2∕W.The SG-DFB consists of a series of grating bursts that are constructed using a periodic apodization function with a burst spacing in the grating of 45 μm,a burst length of 5 μm,and 10 bursts across the total length of the SG-DBR.Transmission results of the through and drop port of the microring resonator show the significant capacity enhancement of the generated center wavelengths.The Q-factor of the microring resonator system,defined as the center wavelength(λ0) divided by 3dB FWHM,without and with integration with the SG-DFB is calculated as 1.93 × 105 and 2.87 × 10~5,respectively.Analysis of the dispersion of the system reveals that increasing the wavelength results in a decrease of the dispersion.The higher capacity and efficiency are the advantages of integrating the microring resonator and the In Ga As P/In P SG-DFB. | S.E.Alavi I.S.Amiri M.R.K.Soltanian R.Penny A.S.M.Supa'at H.Ahmad | 2016 | Chinese Optics Letters2016，14，2： | 1 |
