This also allows the conditions for resonant excitation of a single whispering gallery mode to be determined. The model needs a coupled mode theory which accurately describes the coupling between a straight waveguide and a curved waveguide to be developed. This theory is checked against BPM results.}, title = {Evanescent wave coupling of whispering gallery modes of a dielectric cylinder}, journal = {IEE Proceedings J (Optoelectronics)}, issue = {3}, volume = {140}, year = {1993}, month = {June}, pages = {177-188(11)}, publisher ={}, copyright = {© The Institution of Electrical Engineers}, url = {https://digital-library.theiet.org/;jsessionid=4bs60osl8niu7.x-iet-live-01content/journals/10.1049/ip-j.1993.0028} }
