제8회 광전자 및 광통신 학술회의 (COOC 2001) 논문집,(2001. 5. 16~18). *** 무주 리조트, "" We analyzed the simulated characteristic patterns of the whispering gallery modes generated in a high-Q, wide free-spectral-range dielectric micro-disk resonator and coupled to a submicron-width rectangular waveguide. The excitation input into the FDTD was Sinc function in the time domain and the transmitted output displayed characteristic peaks of resonance wavelength. When we exactly excited the micro-disk resonator with these resonance wavelengths, there existed 1st-, 2nd-, and 3rd-order whispering-gallery modes in the disk which were then coupled out to the waveguide channel.
